# 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.
