MU(VERIFY) User Manuals MU(VERIFY)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-com‐
mand 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) |
