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.

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 verification status 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 unless there is an error.

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.

       When there are no signatures, returns 0 as well.
