ostree-refs List refs
`ostree refs` OPTIONS PREFIX `ostree refs` EXISTING --create=NEWREF

## Description

Lists all refs available on the host. If specified, PREFIX assigns the refspec prefix; default prefix is null, which lists all refs. This command can also be used to create or delete refs.

## Options

`--list`

  For historical reasons, `refs` without this option will strip the specified prefix from the output. Normally, one wants to see the full ref, so providing this option ensures the refs are printed in full, rather than truncated.

`--create`=NEWREF

  Create a ref pointing to the commit EXISTING. NEWREF must not already exist, and EXISTING must be an existing commit. More than one ref can point to the same commit.

`--delete`

  Delete refs which match PREFIX, rather than listing them. If you are trying to reclaim space, you will then need to `ostree prune` or `ostree admin cleanup`.

`--alias`, `-A`

  If used with `--create`, create an alias. Otherwise just list aliases.

`--collections`, `-c`

  Enable interactions with refs using the combination of their collection IDs and ref names. When listing refs, this changes the output format to include collection IDs, and enables listing remote mirrored refs.

  When creating refs, the refspec value passed to the `--create` option is treated as `COLLECTION-ID:REF-NAME` and a mirrored ref is created. (This is an abuse of the refspec syntax.)

  When deleting refs, all refs whose collection ID equals PREFIX are deleted.

## Example
