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.

40 message:
41 $ mu verify msgfile
42
43 To display information about all the signatures:
44 $ mu verify --verbose msgfile

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.

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.
