git-annex-metadata(1) General Commands Manual git-annex-metadata(1) NAME git-annex-metadata - sets or gets metadata of a file 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.
