PROGRAM:
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 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 a field's value, removing any old values.
-s field+=value
Add an additional value, preserving any old values.
-s field-=value
Remove a value.
-s field?=value
Set a value, but only if the field does not already have a value set.
-t tag Set a tag. Note that a tag is just a value of the "tag" field.
-u 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
To set some tags on a file and also its author:
git annex metadata annexscreencast.ogv -t video -t screencast -s author+=Alice
