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) |
