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 par-
       ticularly 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 feeding 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 comments, 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).
