NAME
       pamfile - describe a Netpbm (PAM or PNM) file


SYNOPSIS
       pamfile

       [-allimages] [-count] [-comments]

       [file ...]

       Minimum	unique	abbreviations  of options are acceptable.  You may use
       double hyphens instead of single hyphen to denote options.  You may use
       white space in place of the equals sign to separate an option name from
       its value.


DESCRIPTION
       This program is part of Netpbm(1).

       pamfile reads one or more Netpbm files as input and  writes  out	 short
       descriptions  of	 the image type, size, etc.  This is partly for use in
       shell scripts, so the format is not particularly pretty.

       By default, pamfile reads only the header of the input file.   If  that
       file is a pipe, that might cause problems for the process that is feed-
       ing the pipe.  In that case, see the -allimages option.


OPTIONS
       -allimages
	      This option causes pamfile to describe every image in each input
	      file.   Without  this  option,  pamfile describes only the first
	      image in each input file.

	      This option also causes pamfile to read all the images from  the
	      input  stream, whereas without it, pamfile reads only the header
	      of the first one.	 If the input  stream  is  from	 a  pipe,  the
	      process that is feeding the pipe might require the entire stream
	      to be consumed.  In that case,  use  this	 option	 even  if  the
	      stream contains only one image.

	      This option has no effect if you also specify -count.

	      Note  that  before July 2000, a file could not contain more than
	      one image and many programs ignore all but the first.

	      This option was new in Netpbm 9.5 (July 2000).


       -comments
	      This option causes pamfile to  include  for  each	 PAM  image  a
	      report of the comments from the header of the image.

	      For  a PBM, PGM, or PPM image, pamfile reports there are no com-
	      ments, even if there are.

	      This option was new in Netpbm 10.35 (August 2006).


       -count This option causes pamfile to display only a count of  how  many
	      images are in each input file.

	      As with -allimages, this causes pamfile to read all the images.

	      This option was new with Netpbm 10.31 (December 2005).
