HEADER(1)							     HEADER(1)

NAME
       header - extract fields from mail header

SYNOPSIS
       header [-c] [-n] [-v] [-f fieldname] ...

DESCRIPTION
       The header program reads a mail header on its standard input.  Any text
       that follows the header is ignored.  It then prints all, part, or  none
       of  the	header	to  its standard output, depending on its command line
       options.

OPTIONS
       -c     Match field names only if their  cases  match.   Normally,  mail
	      header field names are case-insensitive.

       -n     Prefix  displayed header fields with their names.	 The resulting
	      output is itself a valid header (albeit possibly	shorter).   By
	      default, only field values are displayed.

       -v     Print only the fields that are not listed in -f options.

       -f fieldname
	      Display (or delete, if -v) header fields with the given name.

SUPPORT
       Please  mail  enhancements, enhancement requests, trouble reports, etc.
       to <chip@pobox.com>.  See also the Debian GNU/Linux bug tracking system
       at http://www.debian.org/Bugs/.
