git-annex-calckey - Man Page

calculate key for a file


git annex calckey [file ...]


This plumbing-level command calculates the key that would be used to refer to a file. The file is not added to the annex by this command. The key is output to stdout.

The backend used is the one from the annex.backend configuration setting, which can be overridden by the --backend option. For example, to force use of the SHA1 backend:

git annex calckey --backend=SHA1 file



Specifies which key-value backend to use.


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.


Makes the --batch input be delimited by nulls instead of the usual newlines.

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