SYNOPSIS

11       mu [common-options] verify [options] <msgfile>

DESCRIPTION

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

VERIFY OPTIONS

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

COMMON OPTIONS

32   -d, --debug
33       makes mu generate extra debug information,  useful  for  debugging  the
34       program  itself.  By  default,  debug information goes to the log file,
35       ~/.cache/mu/mu.log.  It can safely be deleted when mu is  not  running.
36       When running with --debug option, the log file can grow rather quickly.
37       See the note on logging below.
38
39
40   -q, --quiet
41       causes mu not to output informational messages and progress information
42       to standard output, but only to the log file. Error messages will still
43       be sent to standard error. Note that  mu  index  is  much  faster  with
44       --quiet,  so  it  is recommended you use this option when using mu from
45       scripts etc.
46
47
48   --log-stderr
49       causes mu to not output log messages to standard error, in addition  to
50       sending them to the log file.
51
52
53   --nocolor
54       do  not  use ANSI colors. The environment variable NO_COLOR can be used
55       as an alternative to --nocolor.
56
57
58   -V, --version
59       prints mu version and copyright information.
60
61
62   -h, --help
63       lists the various command line options.

EXAMPLES

67       To display aggregated (one-line)  information  about  the  verification
68       status in a message:
69              $ mu verify msgfile
70
71
72
73       To display information about all the signatures:
74              $ mu verify --verbose msgfile
75
76
77
78       If you only want to use the exit code, you can use:
79              $ mu verify --quiet msgfile
80
81
82       which does not give any output unless there is an error.
