NAME
       hed, nohed - edit or remove picture file header

SYNOPSIS
       fb/hed [ -n ] sedcommand input

       fb/nohed input

DESCRIPTION
       Hed  runs  sed(1) with the given sedcommand on the input picture file's
       header.  The resulting picture file is written on standard output.

       Nohed removes the picfile(9.6) header from the input  image.   This  is
       useful mostly for turning a TYPE=dump image into a raw bitmap dump.
