NAME

       mboxgrep - displays email messages matching a pattern

SYNOPSIS

       mboxgrep [OPTIONS] PATTERN [MAILBOX]

DESCRIPTION

       This manual page refers to mboxgrep version 0.7.12a.

       mboxgrep scans a MAILBOX and displays messages matching PATTERN.

       If  a  mailbox  name  is  omitted,  or  a  single dash (-) is given instead, it reads from
       standard input.  It can read mbox folders or output from  another  mboxgrep  process  from
       standard input.

       mboxgrep  understands  POSIX  regular  expressions,  as  well  as  Perl compatible regular
       expressions (if enabled at compile time).  MAILBOX can be either a:

       •      mbox folder (either plain or compressed)

       •      MH folder

       •      Gnus nnmh or nnml folder

       •      qmail-style maildir folder

       -G, --basic-regexp
              PATTERN is a basic regular expression.

       -i, --ignore-case
              Ignore case distinctions.

       -m, --mailbox-format=TYPE
              Select input and output mailbox TYPE.  TYPE can be either `mbox' (default), `zmbox'
              (gzip compressed mbox), `bz2mbox' (bzip2 compressed mbox), `mh', `nnml', `nnmh'  or
              `maildir'.

DEDICATION

       Mboxgrep is dedicated in loving memory of Vicky, my cat who died of tumor on Sep 12, 2002.

       You haven't been long with us, but you gave us a lot of joy and all your  big  heart  that
       stopped ticking too early.  I will never forget you.  Sleep well, little friend.
