NAME

SYNOPSIS

10       mu verify [options] <msgfile>
11
12

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
17       indexed in the database.
18
19       mu verify depends on gpg, and uses the one it finds in  your  PATH.  If
20       you  want  to  use another one, you need to set MU_GPG_PATH to the full
21       path to the desired gpg.

OPTIONS

25       -r, --auto-retrieve
26              attempt to find keys online (see the auto-key-retrieve option in
27              the gnupg(1) documentation).

EXAMPLES

39       To  display aggregated (one-line) information about the signatures in a
40       message:
41          $ mu verify msgfile
42
43       To display information about all the signatures:
44          $ mu verify --verbose msgfile
45
46       If you only want to use the exit code, you can use:
47          $ mu verify --quiet msgfile
48       which does not give any output.

RETURN VALUE

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