mhdr — print message headers

       Leah Neukirchen <leah@vuxu.org>

mhdr prints the headers of the specified msgs.  (See mmsg(7) for the message argument syntax.)

       If no msgs are specified, mhdr will default to the current message.

       If no hdrs are specified, mhdr will print all headers.

       The options are as follows:

       -hhdrs
               Only print the values of headers in the colon-separated list hdrs.

       -pparameter
               Extract a particular RFC 2045 parameter from the specified hdrs.

       -d      Decode the hdrs according to RFC 2047.

       -H      Prefix output lines with the filename of the message, followed by a tab.

       -M      Search for all occurrences of the hdrs (default: only the first).

       -A      Scan for RFC 5322 addresses in the hdrs and print them, one per line.

       -D      Assume header contains RFC 5322 date and print as Unix timestamp.

       The mhdr utility exits 0 on success, 1 if no header was printed, and >1 if an error occurs.

mhdr is in the public domain.
