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"
- Provide the filename to match against. Note that the file
does not have to actually exist on disk.
- Tell what the size of the file is. The size can be
specified with any commonly used units, for example, "0.5 gb" or
- 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.
- Parse the expression as an annex.largefiles expression,
rather than a preferred content expression.
- Tell what the mime type of the file is. Only needed when
using --largefiles with a mimetype= expression.
