git-annex-matchexpression - checks if an expression matches
git annex matchexpression expression [data]
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
- --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.
- Also the
git-annex-common-options(1) can be used.
