git-annex-examinekey - prints information from a key
git annex examinekey [key ...]
This plumbing-level command is given a key, and prints information
that can be determined purely by looking at the key.
- --format=value
- Use custom output formatting.
- The value is a format string, in which '${var}' is expanded to the value
of a variable. To right-justify a variable with whitespace, use
'${var;width}' ; to left-justify a variable, use '${var;-width}'; to
escape unusual characters in a variable, use '${escaped_var}'
- These variables are available for use in formats: key, backend, bytesize,
humansize, keyname, hashdirlower, hashdirmixed, mtime (for the mtime field
of a WORM key).
- Also, '\n' is a newline, '\000' is a NULL, etc.
- --json
- Enable JSON output. This is intended to be parsed by programs that use
git-annex. Each line of output is a JSON object.
- --json-error-messages
- Messages that would normally be output to standard error are included in
the json instead.
- --batch
- Enable batch mode, in which a line containing a key is read from stdin,
the information about it is output to stdout, and repeat.
The location a key's value is stored (in indirect mode) can be
looked up by running:
git annex examinekey $KEY
--format='.git/annex/objects/${hashdirmixed}${key}/${key}'
