HED(9.1)                                                 HED(9.1)

     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 pic-
          ture 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.
