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 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.

       | code | meaning                        |
       |------+--------------------------------|
       |    0 | ok                             |
       |    1 | some non-verified signature(s) |
