SYNOPSIS
git annex metadata [path ...]
DESCRIPTION
The content of an annexed file can have any number of metadata fields attached to it to describe it. Each metadata field can in turn have any number of values.This command can be used to set metadata, or show the currently set metadata.
When run without any -s or -t parameters, displays the current metadata.
OPTIONS
- -g field / --get field
- Get the value(s) of a single field.
- The values will be output one per line, with no other output, so this is suitable for use in a script.
- -s field=value / --set field=value
- Set a field's value, removing any old values.
- -s field+=value / --set field+=value
- Add an additional value, preserving any old values.
- -s field?=value / --set field?=value
- Set a value, but only if the field does not already have a value set.
- -s field-=value / --set field-=value
- Remove a value from a field, leaving any other values that the field has set.
- -r field / --remove field
- Remove all current values of the field.
- -t tag / --tag tag
- Set a tag. Note that a tag is just a value of the "tag" field.
- -u tag / --unset tag
- Unset a tag.
- --force
- By default, git annex metadata refuses to recursively set metadata throughout the files in a directory. This option enables such recursive setting.
- file matching options
- The git-annex-matching-options(1) can be used to specify files to act on.
- --json
- Enable JSON output. This is intended to be parsed by programs that use git-annex. Each line of output is a JSON object.
- --all
- Specify instead of a file to get/set metadata on all known keys.
- --unused
- Specify instead of a file to get/set metadata on files found by last run of git-annex unused.
- --key=keyname
- Specify instead of a file to get/set metadata of the specified key.
EXAMPLES
