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.

EXAMPLES

   To set some tags on a file and also its author:

    git annex metadata  annexscreencast.ogv  -t  video  -t  screencast  -s
   author+=Alice
