# NAME
git-annex lookupkey - looks up key used for file
# SYNOPSIS
git annex lookupkey `[file ...]`
# DESCRIPTION
This plumbing-level command looks up the key used for a file in the
index. The key is output to stdout. If there is no key (because
the file is not present in the index, or is not a git-annex managed file),
nothing is output, and it exits nonzero.
# OPTIONS
* `--batch`
Enable batch mode, in which a line containing the filename is read from
stdin, the key is output to stdout (with a trailing newline), and repeat.
Note that is there is no key corresponding to the file, an empty line is
output to stdout instead.
