NAME

       mu-verify - verify message signatures and display information about them

SYNOPSIS

       mu [COMMON-OPTIONS] verify [OPTIONS] [FILE...]

DESCRIPTION

       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.

       If no message file is provided, the command expects the message on standard-input.

VERIFY OPTIONS

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

   --decrypt
       Attempt to decrypt the message.

COMMON OPTIONS

   -d, --debug
       Makes mu generate extra debug information, useful for debugging the program itself.  Debug
       information goes to the standard logging location; see mu(1).

   -q, --quiet
       Causes  mu  not  to  output  informational  messages  and progress information to standard
       output, but only to the log file. Error messages will still be  sent  to  standard  error.
       Note  that  mu index is much faster with --quiet, so it is recommended you use this option
       when using mu from scripts etc.

   --log-stderr
       Causes mu to not output log messages to standard error, in addition to sending them to the
       standard logging location.

   --nocolor
       Do not use ANSI colors. The environment variable NO_COLOR can be used as an alternative to
       --nocolor.

   -V, --version
       Prints mu version and copyright information.

   -h, --help
       Lists the various command line options.

EXAMPLES

       To display aggregated (one-line) information about the verification status 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 unless there is an error.
