SYNOPSIS

10       mu verify [options] <msgfile>
11

DESCRIPTION

14       mu  verify  is the mu command for verifying message signatures (such as
15       PGP/GPG signatures) and displaying information about them. The sub-com‐
16       mand works on message files, and does not require the message to be in‐
17       dexed in the database.

OPTIONS

21       -r, --auto-retrieve
22              attempt to find keys online (see the auto-key-retrieve option in
23              the gnupg(1) documentation).

EXAMPLES

27       To  display  aggregated  (one-line)  information about the verification
28       status in a message:
29          $ mu verify msgfile
30
31       To display information about all the signatures:
32          $ mu verify --verbose msgfile
33
34       If you only want to use the exit code, you can use:
35          $ mu verify --quiet msgfile
36       which does not give any output unless there is an error.

RETURN VALUE

40       mu verify returns 0 when all signatures could be verified to  be  good,
41       and returns some non-zero error code when this is not the case.
42
43       When there are no signatures, returns 0 as well.
