NAME¶

mu_verify - verify message signatures and display information about them

SYNOPSIS¶

mu verify [options] <msgfile>

DESCRIPTION¶

mu verify is the mu command for verifying message signatures (such as PGP/GPG signatures) and displaying information about them. The sub-command works on message files, and does not require the message to be indexed in the database. mu verify depends on gpg, and uses the one it finds in your PATH. If you want to use another one, you need to set MU_GPG_PATH to the full path to the desired gpg.

OPTIONS¶

-r, --auto-retrieve

attempt to find keys online (see the auto-key-retrieve option in the gnupg(1) documentation).

EXAMPLES¶

To display aggregated (one-line) information about the signatures in a message:

   $ mu verify --verbose msgfile

To display information about all the signatures:

   $ mu verify --verbose msgfile

If you only want to use the exit code, you can use:

   $ mu verify --quiet msgfile

which does not give any output.

RETURN VALUE¶

mu verify returns 0 when all signatures could be verified to be good, and returns some non-zero error code when this is not the case.
