NAME
     mhdr -- print message headers

SYNOPSIS
     mhdr [-h hdrs [-p parameter]] [-d]	[-H] [-M] [-A |	-D] [msgs ...]

DESCRIPTION
     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:

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

     -p	parameter
	     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.

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