## Basic Usage

### Selecting Files and Folders

You can select files and folders in several ways in &app;. Typically this is achieved by clicking on the files using the mouse, as explained in gcmd-TBL-10.

### Selecting Items in the File Manager

Task | Action | Default key bindings
Select an item | Click on the item. | SPACE INSERT
Select a group of contiguous items | In icon view, drag around the files that you want to select. In list view, click on the first item in the group. Press-and-hold SHIFT, then click on the last item in the group. |
Select multiple items | Press-and-hold CTRL. Click on the items that you want to select. Alternatively, press-and-hold CTRL, then drag around the files that you want to select. |
Select all items in a folder | Choose Mark Select All. | CTRL A CTRL+
Unselect all items in a folder | Choose Mark Unselect All. | CTRL SHIFT A CTRL-
Select all files with the same extension |  | ALT NUM +
Unselect all files with the same extension |  | ALT NUM -
Select files using a pattern | Choose Mark Select with Pattern. &app; selects files matching a pattern based upon their file name using either wildcards or regular expressions. | NUM +
Unselect files using a pattern | Choose Mark Unselect with Pattern. &app; unselects files matching a pattern based upon their file name using either wildcards or regular expressions. | NUM -
Invert selection | Choose Mark Invert Selection. | NUM *

To perform the default action on an item, double-click on the item.

### Drag-and-Drop

You can drag and drop selected items from one pane to the other to copy, move, or create a symbolic link to an item. You can also drag and drop the selected items into another application.

To drag and drop a selection or a selected item with your mouse, with the pointer over the selection or the item, press the left button and keep it depressed, move the mouse pointer to the target location and release the left button.

- By pressing the SHIFT key while you release the mouse button you can move the selection instead of copying it.

- By pressing the CTRL SHIFT keys while you release the mouse button you can create symbolic link to the selection instead of copying it.

When not pressing a key while dropping the selection, the default is to query for the action to be executed, i.e. copy, move or create a symbolic link. In the &app; options you can change that behavior to copy or to move the selection. See also under gnome-commander-prefs-confirmation.

### Copying a File or Folder

You can use the mouse, the keyboard and the menus to copy a selection of items in another location.

First select the item(s) you wish to copy, You can then use any of the the following options.

- To copy using the menus Edit Copy, then select the location where you want to copy the selection and select Edit Paste.

- Using the mouse You can also right click on the selected items in the drop down menu select Copy then in the chosen location Right click in an empty area and select Paste in the drop down menu.

- Press the following keys CTRL C, then select the location for the files and press CTRL V

- To copy the selection from one pane to the other using the mouse simply drag and drop the selected items to the other pane.

- To copy the selection from one pane to the other you can simply press F5.

The first three options will allow you to copy into another application than &app;.

### Moving a File or Folder

You can use the mouse, the keyboard , and the menus to move a selection of items in another location

First select the item(s) you wish to move, You can then use any of the the following options.

- To move using the menus Edit Cut, then select the location where you want to copy the selection and select Edit Paste.

- Using the mouse you can also right click on the selected items in the drop down menu select Cut then in the chosen location right click in an empty area and select Paste in the drop down menu.

- Press the following keys CTRL X, then select the location for the files and press CTRL V

- To move the selection from one pane to the other using the mouse drag and drop the selected items to the other pane and press the SHIFT while releasing the left mouse button.

- To move the selection from one pane to the other can simply press F6.

With the first three options it is possible to move marked items into another application.

### Renaming a File or Folder

This section describes a simple way to rename files or folders. There is also the gnome-commander-advanced-rename for more complex operations and batch processing. You can use various the following methods to rename files and folder.

Firstly select the item you wish to rename.

- Right click on the item and select Rename, type in the new name, and press Enter when finished.

- Press F2 and then type in the new name and press Enter when finished.

- You can also use the menus: select File Properties and rename the file using the properties dialog.

### Deleting a File or Folder

There are different ways to delete an item using &app;.

- Press the F7, in the dialog box that is then opened name the new folder.

- Using the mouse right click in an empty area of the pane, in the drop down menu select New Folder, then type the folder name in the dialog box that is opened.

### Creating a Symbolic Link to a File or Folder

A symbolic link is a special type of file that points to another file or folder. When you perform an action on a symbolic link, the action is performed on the file or folder to which the symbolic link points. However, when you delete a symbolic link, you delete the link file, not the file to which the symbolic link points.

There are three different ways to create a symbolic link to a file or folder:

- Select the file or folder to which you want to create a link. Choose File Create Symbolic Link.

- Grab the item to which you want to create a link, then press-and-hold CTRL SHIFT. Drag the item to the location where you want to place the link.

- Select the file or folder to which you want to create a link. Press CTRL SHIFT F5.

The permissions of a symbolic link are determined by the file or folder to which a symbolic link points.

For more on dragging items, see gnome-commander-dnd.

### Using multiple tabs

You can open multiple tabs in both panels to speed up navigation. &app; can store the open tabs location upon closing. When you restart the application the tabs are reopened as they were before. This option can be set in gnome-commander-prefs-general.

Using the mouse the middle click can be configured to open a new tab. This option can be set in gnome-commander-prefs-general. When it is set a middle click on a folder will open it in a new tab in the same pane.

When using a 2 button mouse the middle click is emulated by clicking both buttons simultaneously

- To open a new tab press CTRL T this opens a new tab in the current panel with the same folder opened.

- To open a new tab displaying the selected folder in the current pane press the CTRL UP. If you have configured the mouse middle click option to open a new tab (gnome-commander-prefs-general), then using the middle mouse button on a folder will also open a new tab displaying it in the current pane.

- To open a new tab displaying the selected folder in the inactive pane press the CTRL SHIFT UP.

- To navigate between tab you can you the mouse or use CTRL TAB as many time as needed to select the tab element. If the tabs are selected you can also use the RIGHT or LEFT to select the desired tab.

- To close a tab you can use the mouse and double click the tab or right click on it and from the menu select Close tab. You can also close the current tab using the keyboard shortcut CTRL W

Right clicking on any tab will open a tab specific menu

- Open in new tab this action opens a new tab with the displaying the currently opened folder.

- Refresh tab this actions refreshes the files displayed currently in the folder.

- Copy tab to other pane opens a new tab in the opposite pane, this tab will display the selected tab.

- Close tab this action closes the currently selected tab.

- Close all tabs &app; will close all open tabs in the current pane. This leaves the current tab as the only open folder.

- Close duplicate tabs &app; will search for duplicated open tabs in the current pane and close them.

1. Select the file or folder whose properties you want to view. Now you can

- Press ALT ENTER.

- Choose File Properties....

- Right-click on the file or folder and choose Properties....

#### File Properties dialog

Shows file properties dialog.

On the Permissions tab (see permission-tab-fig), you can change the permissions and ownership of a file (that is, if you have the right permissions yourself).You can change the read, write, and execute settings for a file. For more information on permissions, see gnome-commander-permissions.

The following table lists the properties that you can view or set for files and folders, the exact information shown depends on the object type:

Property | Description
Name | The name of the file or folder.
Location | The location of the file or folder.
Volume | The name of the volume in which the file or folder is located.
Free space | The amount of free space on the volume.
Type | The type of object, file or folder.
MIME Type | The official naming of the type of file.

Modified | The date and time at which the object was last changed.
Accessed | The date and time at which the object was last viewed.
Size | The amount of data occupied by object, file or folder.
Metadata | If available, additional metadata information is shown for file types like images, documents or audio files. The shown tags are: File.Description, File.Publisher, Doc.Title, Doc.Pagecount, Audio.Albumartist, Audio.Title, Audio.Bitrate and Audio.Durationmmss. For more information, see metadata tags.

### Changing Permissions

To change the permissions of a file or a folder, perform the following steps:

1. Select the file that needs its permission modified.

2. Open the properties window with your favorite method (e.g. ALT ENTER).

3. Click on the Permissions tab.

4. To change the file's group, choose from the groups the user belongs to in the drop-down selector.

   Property | Description
   Read | The users can read a file.
   Write | The users can save a file.
   Execute | The users can run a file as a program.

#### File Permissions dialog

Shows file permissions dialog.

### Using Bookmarks

You can use bookmarks to speed up navigation within your local files or to access remote servers.

Managing your bookmarks is done with the bookmark manager, started by selecting Bookmarks Manage bookmarks... or pressing CTRL D. See an example screenshot below.

To add a folder to the bookmarks, navigate to the folder's location. In the menu select Bookmarks Bookmark this directory. Once you have added a bookmark, it will be added in its respective group in the Bookmarks menu. A bookmark is automatically assigned to a group, depending on where the bookmark is pointing to.

You can then Jump to a bookmark, Edit, Remove, or modify the position of a bookmark in the selected group.

In the bookmark list there are four different columns displayed:

1. The name of the bookmark group,

2. The name of the bookmark,

3. The shortcut of the bookmark,

4. The path to which the bookmark points to.

The name and the path of a bookmark are editable by pressing the Edit button. In contrast, the shortcut of a bookmark in the third column is taken from the associated user action Go to bookmarked location, adjustable by clicking on the menu entry Settings Keyboard Shortcuts... . In the bookmarks window it is only shown as a reference but it is not editable.

#### Bookmark Management Dialog

Shows bookmark management dialog.

### Hidden Files and Folders

By default, &app; does not display certain system and backup files in folders. This prevents accidental modification or deletion of them, which can impair the operation of your computer, and also reduces clutter in locations such as your Home Folder. &app; does not display:

- Hidden files, whose file name begins with a period (.),

- Backup files, whose file name ends with a tilde (~) or with extension `'.bak'`

- Files that are listed in a particular folder's `.hidden` file.

You may hide or show hidden files in all folders by:

- Selecting View Show Hidden Files,

- Pressing CTRL SHIFT H.

### Advanced file renaming

A powerful tool for batch renaming of the files selected in &app;. It allows to easily rename lots of files in one go. The file names can be created by parts of the original file name, its path, numbering the files or accessing hundreds of informations about the file, like creation date or Exif/IPTC informations of an image.

When started, the following dialog is displayed:

#### Advanced Rename Tool Dialog

Shows advanced file renaming dialog.

Template

- Specifies template for file renaming. All ordinary characters placed in the format string go into the new name without conversion. Conversion specifiers are introduced by a few placeholders (see below for the detailed list). Additionally g_date_time_format() format controls are also accepted - except for "%D", "%n" and "%t" for obvious reasons. If found, they are left intact.

Counter

- Specifies settings for counters: start value, step and width ('auto' = automatic width, '1',..., '16': fixed width).

Regex replacing

- List of the regular expression patterns. The patterns are matched against Template. If matched, patterns are replaced with their corresponding replacements. The order of execution is top-bottom. Invalid or broken regex patterns will be marked red.

Case

- Changes the case of the selected file names.

Trim blanks

- Removes leading and trailing whitespace from the selected file names.

Results

- List of the new file names. The list can be reordered using drag-and-drop. The context menu provides options for: removing file from the list, viewing file or its properties, and refreshing the list. Conflicting renames will be marked red.

Apply

- Starts to rename files. Conflicting renames will be marked red.

Close

- Closes the dialog without file renaming.

Reset

- Resets current settings to defaults.

Profiles...

- Shows options for profile management. A profile is a collection of advanced file renaming parameters (template, counter, regex patterns, case conversions and blank trimming) identified by its name. You can define as many different profiles as you require.

#### Template Placeholders

Placeholder | Replacement
$N | The whole file name (with extension)
$N(range) | Part of the whole file name (with extension)
$n | File name without extension
$n(range) | Part of the file name without extension
$e | File extension
$e(range) | Part of the file extension
$p | Parent dir name
$p(range) | Part of the parent dir name
$g | Grandparent dir name
$g(range) | Part of the grandparent dir name
$c | File counter
$c(width) | File counter with specified digit number (width)
$c(a) | File counter with digit number (width) calculated automatically
$x | Hexadecimal random number (8 lowercase digits)
$x(width) | Hexadecimal random number with specified lowercase digit number (width)
$X | Hexadecimal random number (8 uppercase digits)
$X(width) | Hexadecimal random number with specified uppercase digit number (width)
$T(metatag) | Metadata tag
$$ | A literal "$" character

Broken - like $n(), $e(0,-3) or $N(abc) - or unknown placeholders are copied verbatim without any substitution.

#### Metadata Tags (Metatags)

Metadata is usually defined as data about data. Metadata describes data about files that is often user visible in file managers, office applications, document viewers and audio players. Metadata can typically be viewed or written by selecting "properties" from the file menu of one of these applications.

For all metadata, each metadata tag (metatag) needs to be namespaced with its class type using a "." qualifier (e.g. `Audio.Artist` represents the metadata Artist for an audio class file).

The placeholder for metadata is `$T(metatag)`. Use, for example, `$T(Exif.DateTime)` to get image capture date/time and to insert it to new filename (metatags names are case insensitive, so we could use also `$T(exif.datetime)` here). The generic `'Audio.'`, `'Doc.'`, `'File.'` and `'Image.'` metatags are independent of the used framework and they provide unified access to respectively audio, doc, file or image metadata. Please refer to freedesktop.org for more details on the generic metatags.

The unused portion of the area is padded with NULL ("00.h"). ID codes are assigned by means of registration. The value of CountN is determinated based on the 8 bytes in the character code area and the number of bytes in the user comment part. Since the TYPE is not ASCII, NULL termination is not necessary. The ID code for the `Exif.UserComment` area may be a Defined code such as JIS or ASCII, or may be Undefined. The Undefined name is UndefinedText, and the ID code is filled with 8 bytes of all "NULL" ("00.H"). An Exif reader that reads the `Exif.UserComment` tag must have a function for determining the ID code. This function is not required in Exif readers that do not use the `Exif.UserComment` tag. When a `Exif.UserComment` area is set aside, it is recommended that the ID code be ASCII and that the following user comment part be filled with blank characters [20.H].
Exif.WhiteBalance | White Balance | The white balance mode set when the image was shot.

The color space is declared in a color space information tag, with the default being the value that gives the optimal image characteristics Interoperability this condition.
Exif.YCbCrPositioning | YCbCr Positioning | The position of chrominance components in relation to the luminance component. This field is designated only for JPEG compressed data or uncompressed YCbCr data. The TIFF default is 1 (centered); but when Y:Cb:Cr = 4:2:2 it is recommended that 2 (co-sited) be used to record data, in order to improve the image quality when viewed on TV systems. When this field does not exist, the reader shall assume the TIFF default. In the case of Y:Cb:Cr = 4:2:0, the TIFF default (centered) is recommended. If the reader does not have the capability of supporting both kinds of `Exif.YCbCrPositioning`, it shall follow the TIFF default regardless of the value in this field. It is preferable that readers be able to support both centered and co-sited positioning.
Exif.YCbCrSubSampling | YCbCr Sub-Sampling | The sampling ratio of chrominance components in relation to the luminance component. In JPEG compressed data a JPEG marker is used instead of this tag.

Non-existent metatags are expanded to empty strings.

#### Ranges

Ranges are a method of accessing a part of a string. The concept of ranges is based on python slices.

A range (start_index:end_index) starts at the start_index and finishes one character before the end_index.

Range syntax

- (start_index:end_index)

- (start_index) ≡ (start_index:)

- (start_index,length) ≡ (start_index:start_index+length)

If one of the indices is dropped, it is assumed that you want everything in that direction. I.e. (:3) means "every character from the beginning of the string up to character 3, non-inclusive." (3:) would, on the other hand, mean "every character from the string, starting at character 3 (inclusive) up to, and including, the last one." If index is negative, it is relative to the end of the string. Index -3 stands for "the third character from the end of the string".

Position of the first letter is '0'.

### Remote Connections

The Remote Connections dialog gives an overview about the stored connections to remote servers. It is also your starting point for opening a connection to a remote server.

Open the dialog by clicking Connections Remote Server... in the menu bar or by hitting CTRL F.

It is divided into four parts:

1. Connections list,

2. Buttons to Add, Edit and to Remove a selected connection,

3. Option for setting the anonymous FTP password globally.

4. A Close and a Connect button.

Double click on a connection or select a connection and hit ENTER will open the remote connection in the active pane of &app;.

An example figure with three anonymous FTP and one secure SSH connection is shown below.

In the subsection gnome-commander-config-remote-connections it is shown how to edit a connection by clicking on the Add or Edit button.

#### Remote Connections Overview

Overview of remote servers.

#### Adding and Configuring Remote Connections

Remote connection details can be set up temporarily or permanently, depending on how they are added to &app;:

- By hitting the shortcut CTRL N a temporary connection is configured. That's why no connection alias is needed in this case. If you restart &app;, the connection details have to be entered again to connect to the same server.

- By adding a remote connection via the Add button in the Remote Connections dialog (see above), the connection is stored permanently in this dialog. If you restart &app; the stored connection is available again.

Currently, (&app; version 1.4) there are six different connection types available:

1. SSH

2. Public FTP

3. FTP (with login)

4. Windows share

5. WebDAV (HTTP)

6. Secure WebDAV (HTTPS)

7. Custom location

Depending on the choice, different login details have to be entered in the Remote Server dialog.

See an example for a public FTP server in the figure below.

##### Creating Server Connection

Creating a new remote server connection.

### Using the Internal Viewer

The internal viewer allows viewing contents of files in text, Unicode, binary, hex or graphical mode.

To start viewing files use F3 (default viewer - defined in Settings Options...) or SHIFT F3 (internal viewer). The internal viewer uses MMAP whenever possible for the fastest file loading.

#### View Modes

The View Modes group (In the View menu) contains the preferences that you can set to view images and texts in the internal viewer window:

1. Text mode

2. Binary mode

3. Hex dump mode

4. Image mode

For all of the three text modes (mode 1 to 3) you can change the text encoding in Text Encoding.

For the image display mode you can choose if additional meta data should be shown below the image by selecting Image Show Metadata Tags.

Below of the View Modes in the View menu you can set the zoom factor. You can

- Zoom in (CTRL+),

- Zoom out (CTRL-),

- Zoom to normal size (CTRL 0), or

- Fit the image into the window of the internal viewer.

#### To Scroll an Image

To scroll around an image that is larger than the image window or full screen window, you can use the following methods:

- Use the arrow keys on the keyboard.

- Drag the scrollbars on the window borders.

- Move the mouse scroll wheel for up/down movement; CTRL+mouse wheel for left/right movement

- Click at a random position of the image and drag it by pulling your mouse in the opposite direction to which you want to scroll. For example, if you want to scroll down the image, drag the image upwards.

#### Keyboard mappings

Shortcut | Mapping
Escape CTRL Q | Closes the internal viewer window
W | Toggles line wrapping (applicable only in text display modes)
T ALT ENTER | Shows metadata tags
Input Modes:
A | Sets ASCII input mode. When in ASCII mode, you can also set the required character encoding from the "View|Character Encoding" submenu
Q | Sets ASCII input mode, with codepage 437 encoding (suitable for binary and hex mode viewing)
U | Sets UTF-8 input mode
Display modes:
1 | Sets display mode to text, with fixed width font
2 | Sets display mode to binary. Switching to Binary display mode will automatically set ASCII input mode (UTF-8 is not supported with binary display)
3 | Sets display mode to hex dump. Switching to hex display mode will automatically set ASCII input mode (UTF-8 is not supported with hex dump display)
4 | Tries to load the file as an image. Loading is done using GDK, so every GDK-supported format should work.
Zooming:
CTRL+ | Zooms in or increment the font size
CTRL- | Zooms out or decrement the font size
CTRL 0 | Sets normal size
Image manipulation:
CTRL R | Rotates the image 90° (applicable only in IMAGE display mode)
CTRL SHIFT R | Rotates the image 270° (applicable only in IMAGE display mode)
Image manipulation:
CTRL S | Saves the current window size, input mode, and other settings as the default. Starting display mode is determined by the file's content, and is not saved as a user setting.

- Default this is the text and background colors used by default. These colors are used for standard unselected items.

- Alternate If you wish to have a different color on alternate rows to help distinguish the files you can change the colors defined here. By default they are set to the same colors as the default.

- Selected File, all selected items will be marked using the colors defined here. They differ from the default to help visualization of the marked items.

- Cursor is the row currently activated. This highlights the position and is useful when navigating files with the keyboard.

See the example figure of the Edit Colors... dialog below.

##### Configuring Custom Colors

Shows &app; dialog for editing custom colors.

#### Configuring Custom LS_COLORS

&app; does not differentiate files types by default.

You can configure it to differentiate file types like LS_COLORS does when using the command shell. For more information on this you can look up the dir_colors man page.

To enable the use of LS_COLORS for &app; click on Settings Options, than on the Layout tab and activate the Colorize files according to the LS_COLORS environment variable check box.

For this you will need to find out the default TERM value of your system. Therefore, login to a virtual terminal by pressing CTRL ALT F1 and execute the command echo $TERM. If the output is linux, the entry in ~/.profile might look like this:

       # Set colors
       export TERM=linux
       test -r ~/.dir_colors && eval "$(dircolors -b ~/.dir_colors)"

### Tabs

The tabs preferences tab allows you to configure parameters for tabs.

| Requires terminal | Whether the application requires a terminal to be opened. In this case &app; starts the application in an independent terminal.
Show for | All files | When this option is selected right clicking on any file will display the application in the contextual menu.
| All directories | When this option is selected right clicking on any directory will display the application in the contextual menu.
| All directories and files | When this option is selected right clicking on any file or directory will display the application in the contextual menu.
| Some files | When this option is selected right clicking on the files specified in the File patterns below will display the application in the contextual menu.
| File patterns | This contains the file extensions specific to the application. The syntax is as follow: "*.extension" use ";" as a separator between the different extensions if there are more than one.

### Devices

This section of the option dialog lets you configure devices so that you can access them by pressing a button in the device buttons toolbar or an entry in the connections menu.

This can be useful if you have configured devices through your fstab file. In this case, these devices might not be shown automatically in the devices buttons toolbar.

- In the Devices window all devices which have been added manually are shown together with their icon.

- Below the Devices window you have two options:

  - Show Samba workgroups icons: If activated, a SMB workgroups icon will be shown in the device buttons toolbar.

  - Show only the icons: If activated, device icons are shown without their alias name in the device buttons toolbar.

On the right hand side there are five buttons, described in the gcmd-dev table below.

#### Devices options

Shows &app; devices preferences dialog.

### Devices tab

Header | Option | Description
Devices: | Add: | You can add a device by pressing this button. The device defined here will appear in the device buttons toolbar and an entry in the connections menu. A dialog box is opened when you click on this button.
| Edit: | Clicking this button will open a dialog were you can modify a device which is selected in the Devices window list.
| Remove: | Clicking this button will remove the application selected from the Devices window list.
| Up: | Clicking this button will move the device up in the list. This will also affect the order in which the list is displayed in the contextual menu.
| Down: | Clicking this button will move the device down in the list. This will also affect the order in which the list is displayed in the contextual menu.

The dialog box used to add new and to modify existing devices is the same. The explanation for this one follows below.

### Devices option tab

Header | Option | Description
Alias: |  | This text box contains the label that is displayed in the contextual menu.
Device/Label: |  | This text box contains the device which should be accessed. Usually it is located in the /dev directory, so you can for example write /dev/sdx1 here. The device would then be mounted via "mount /dev/sdx1". On the other hand you can also add a label of a device which you have configured in the system fstab. If the string entered in the text box does not start with a "/" character (e.g. Media), the device is mounted with "mount -L" (e.g. "mount -L Media").
Mount point: |  | Here you specify where the device should be mounted to, so that Gnome Commander knows where to jump to when the mount was successful, for example /mnt/cdrom.
Icon |  | By clicking on the button you can specify the icon which should be displayed in the contextual menu.

## Keyboard Shortcuts

In this section the keyboard shortcuts in &app; are presented. In the table below you will find each keyboard shortcut, its mappings and an info if it is user definable.

If you want to know more about how to change a keyboard shortcut or how to assign a new one (if user definable), look at the section gnome-commander-user-actions.

The daily usage of &app; is very effective if you know by heart at least the most important keyboard shortcuts for moving and file handling (see section gnome-commander-usage). Learn them and &app; will be an even more effective tool for you.

Some keyboard shortcuts may not work as expected under your environment, e.g. GNOME. The reason for that is that the environment uses some global shortcuts (i.e. ALT F7 moves the entire application window in GNOME), which suppresses assigned keyboard mapping of &app;. Use the keyboard shortcuts preference tool of your environment to customize the default keyboard shortcuts to your requirements.

## User Actions

User actions trigger predefined functions (actions) and make &app; very flexible. They are accessed by a key or set of keys (shortcut key).

### Managing user actions

The menu for user actions and associated keyboard shortcuts can be opened by clicking on Settings Keyboard Shortcuts.... Below, the usage of the dialog is Keyboard Shortcuts... explained.

In the keyboard shortcut dialog a table with three columns is shown:

1. Shortcut Key: Key combination the user has to press to perform the action.

2. Action: Action to perform by pressing the shortcut key.

3. Options: Some user actions require an option to perform the action, e.g. the command to be executed by the "Execute command" action.

You can Add a new shortcut and Remove a selected one with the related buttons on the right.

The default dialog window is shown in the figure keyboard-shortcuts below.

Available user actions are shown in the table gnome-commander-user-actions-list below.

Find the default key bindings in the previous section gnome-commander-keyboard.

It's possible to assign more than one key combinations to an action. To do so, click on the Add button, choose a new shortcut and choose the action which is already assigned to another shortcut. Some actions are already assigned to multiple shortcuts by default.

Key bindings are stored in the <KeyBindings> section of &app; config file (~/.gnome-commander/gnome-commander.xml).

## Additional Pop-up Menu Actions

### Introduction

The pop-up menu of &app;, which can be opened by right-clicking on a file or folder or by pressing SHIFT F10, can be easily extended by putting executable files into ~/.config/gnome-commander/scripts/. For each file in this directory a separate entry in the pop-up menu will be displayed. When such a menu entry is clicked, the associated script will be executed with the names of all selected items as arguments. When the SHIFT key is pressed while clicking the pop-up menu entry, the script will be called separately for each selected file.

#### Example picture of the pop-up menu with four additional entries

### File format

The files can be binary or simple text files. In the latter case it is possible to handle some config variables over to &app; by using a key-value format: #[key]: [value], with '#' being the first character in a text line.

Currently, the following keys are implemented:

name | The label of the menu item | If undefined, the script file name will be used
term | Run the script in a terminal window | To activate this, set value to 'true'

### Example Pop-up menu scripts

Some example scripts can be found online in the &app; git repository.

## Tips and Tricks

Some very simple tips and tricks on using and getting the most out of &app;.

### Handling Archives

&app; still lacks built in browsing of compressed archives. However the program can be configured so that working with archives becomes quite practical anyway.

There are two different ways: The preferred one is to activate the build in Fileroller plugin in the menu Plugins Configure Plugins.... By activating this plugin you get additional entries in the popup menu by right clicking on selected files and folders (make sure that Fileroller is installed in your system). By clicking on an archive, the popup menu lets you choose where to extract the archive to.

The second, outdated but still working way is the following:

- If you don't already have the program Fileroller, download it and install it.

- Open the Options dialog and go to the Programs tab.

- Add two favorite apps using the values shown in the figures below.

You can now right click any file or folder and choose Create archive... to compress it and right click compressed files and choose Extract archive... to extract it.

#### Create Archive

This entry allows creating archives easily.

#### Extract Archive

This entry allows extract archives easily.

### Copying File Names and Paths

- To copy names of selected files to the environment's clipboard, use the Copy File Names action on the Edit menu or the "**" icon on the toolbar.

- To copy full paths of selected files to the environment's clipboard, hold down SHIFT while activating either the Copy File Names action on the Edit menu or the "**" icon on the toolbar.

- To copy the full path of the current directory, right click on the directory indicator at the top of the directory list.

- To insert the current file's path in Gnome Commander's command line, press CTRL Shift Enter.

- To insert the current file's name in Gnome Commander's command line, press CTRL Enter.

## &app; Installation

### Getting &app;

It's recommended to use the &app; package that is provided by your distribution. Refer to &app; for the list of distributions supporting &app; packages.

All current and historical releases can be found on the GNOME FTP server, too.

### Versioning

&app; is being developed in a stable and a testing branch, where the test releases fill the purpose of testing new ideas. Successful ones will then get backported to the stable branch. The version numbers (major, minor and micro) follows the quite usual standard of odd and even versioning, where odd minor versions stands for the unstable releases and the even numbered branch eventually gets the thoroughly tested new functions backported.

### Current stable version

If you'd like to compile the latest stable version of &app; yourself, get it as a tar.xz file from the download section on the &app; home page.

After extracting the archive, first have a look at the README file, where you get an overview of the downloaded release. Also, have a look at the INSTALL file. The installation is explained in detail there.

### Development version

For those of you who feel really adventurous, or maybe want to hack on the freshest code, the latest development source snapshots are available by using GIT:

`git clone https://gitlab.gnome.org/GNOME/gnome-commander.git`

The above works only to do a first time download and not for updating the code, if you already have a version of the code simply run `git pull` to get the latest revisions.

Just remember to run `./autogen.sh` before building by `make`.

Be aware that there can be serious bugs in code from GNOME git repository. This code is intended for hacking, development and testing purposes only.

## Configuration Files

This section gives an overview of the configuration files used by &app;:

Since &app; version 1.10.0 the location of configuration files changed from ~/.gnome-commander to ~/.config/gnome-commander. Existing files are automatically moved when starting &app; 1.10.0 the first time.

~/.config/gnome-commander/scripts/*

In this directory the user can place scripts for the popup-menu-actions.

Since &app; version 1.10.0 the following option files are obsolete. If they have been created by ealier &app; versions then the filename is extended automatically by *.deprecated and their settings are imported in GSettings under the path org.gnome.gnome-commander.

~/.config/gnome-commander/devices

~/.config/gnome-commander/fav-apps

~/.config/gnome-commander/gnome-commander.xml

Since &app; version 1.6.0 the options file ~/.gnome2/gnome-commander is obsolete. The settings of this file are now stored in GSettings under the path org.gnome.gnome-commander.

## Known Bugs and Limitations

You can report or view &app; bugs at gitlab.gnome.org.

Some words about bugs: Though &app; is relatively free from bugs and is a quite mature program, no programs will ever be totally bug free. New bugs can be introduced with new features, or through other programs and libraries it depends on, this goes especially for development and testing versions. Quality bug reporting is very important and can be a very good help for the developers to make a better program. Bug reporting is not an act of dissatisfaction, so you are very welcome to help us find, hunt down and kill the bugs. Testing of the new releases and bug reporting is the best way users without programming knowledge can help out in the development of a program, and those with programming knowledge are very welcome to suggest fixes and/or send patches to the developers, all in the spirit of free and open source software.

Known limitation:

- &app; is still lacking on GVFS/GIO support. Instead it uses GnomeVFS.

- Configuration of default application depending on the files MIME type is broken and was finally removed in v1.4. See section gnome-commander-mime-types for more information.

Given enough eyeballs, all bugs are shallow.

## About &app;

### History of &app;

&app; was primarily written by Marcus Bjurman, who was the one initiating this project in 2001 and developed it up to version 1.1.6 in January 2004.

Later on, since 2004, &app; was maintained by the new lead developer Piotr Eljasiak, working at the project already since 2002. In this time, Assaf Gordon contributed by implementing the internal file viewer.

Piotr conducted the development until version 1.2.8.15. In this time Magnus Stålnacke was responsible for the homepage. On the mailing list, amongst others, Michael and Magnus contributed with many great ideas and by helping finding bugs and other inconsistencies. After Magnus resigned from the project, Thomas Jost helped to maintain the homepage at Savannah.org

Unfortunately, Piotr suddenly passed away in the beginning of 2012 and &app; had no maintainer for nearly two years. Late in 2013, Uwe Scholz, a user of &app; since the days before version 1.0, took over the project as project maintainer.

### Location

In the beginning, &app; had its home at Sourceforge. Later, the project moved to Savannah.org, where it got its own homepage and its mailing lists. In the end of 2003, the source tree moved to Gnome.org. Though, the homepage and mailing lists were still hosted at Savannah.

Since 2013, the location of the &app; home page has been moved to GitHub.org.

### Bug Reporting

If you found a bug, you can check if it is already reported on our GitLab page at Gnome.org. If not, please report the bug. If you want to fix it by yourself have a look at the section gnome-commander-development-version.
