mu verify− verify message signatures and display information about them
mu verify [options] <msgfile>
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.
attempt to find keys online (see the auto-key-retrieve option in the gnupg(1) documentation).
aggregated (one-line) information about the verification
status in a message:
$ mu verify msgfile
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.
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.
