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.
