NAME

       git-annex-matchexpression - checks if an expression matches

SYNOPSIS

       git annex matchexpression expression [data]

DESCRIPTION

       This  plumbing-level  command  is given a preferred content expression, and some data, and
       checks if the expression matches the data. It exits 0 if it matches, and 1 if not. If  not
       enough data was provided, it displays an error and exits with special code 42.

       For example, this will exit 0:

        git annex matchexpression "include=*.png and largerthan=1mb" --file=foo.png --size=10mb

OPTIONS

       --file=

              Provide the filename to match against. Note that the file does not have to actually
              exist on disk.

       --size=
              Tell what the size of the file is. The size can be specified with any commonly used
              units, for example, "0.5 gb" or "100 KiloBytes".

       --key= Tell  what  key  is  being matched against. This is needed for matching expressions
              like "copies=N" and "metadata=tag=foo" and "present", which all need to look up the
              information on file for a key.

              Many  keys  have  a  known size, and so --size is not needed when specifying such a
              key.

       --largefiles
              Parse the expression as an annex.largefiles expression,  rather  than  a  preferred
              content expression.

       --mimetype=
              Tell  what the mime type of the file is. Only needed when using --largefiles with a
              mimetype= expression.

       --mimeencoding=
              Tell what the mime encoding of the file is. Only  needed  when  using  --largefiles
              with a mimeencoding= expression.

       --explain
              Display  explanation  of  what parts of the preferred content expression match, and
              which parts don't match.

       Also the git-annex-common-options(1) can be used.
