OpenSolaris 2009.06 - man page for postreverse (opensolaris section 1)

postreverse(1)				  User Commands 			   postreverse(1)

NAME
       postreverse - reverse the page order in a PostScript file

SYNOPSIS
       postreverse [-o list] [-r] [file]

       /usr/lib/lp/postscript/postreverse

DESCRIPTION
       The  postreverse  filter  reverses the page order in files that conform to Adobe's Version
       1.0 or Version 2.0 file structuring conventions, and writes the results	on  the  standard
       output.	Only one input file is allowed and if no file is specified, the standard input is
       read.

       The postreverse filter can handle a limited class of files that violate page independence,
       provided  all  global definitions are bracketed by %%BeginGlobal and %%EndGlobal comments.
       In addition, files that mark the end of each page with %%EndPage: label	ordinal  comments
       will  also reverse properly, provided the prologue and trailer sections can be located. If
       postreverse fails to find an %%EndProlog or %%EndSetup comment, the entire file is copied,
       unmodified, to the standard output.

       Because	global	definitions  are extracted from individual pages and put in the prologue,
       the output file can be minimally conforming, even if the input file was not.

OPTIONS
       -o list	  Select pages whose numbers are given in the comma-separated list. The list con-
		  tains  single  numbers N and ranges N1 - N2. A missing N1 means the lowest num-
		  bered page, a missing N2 means the highest. The page range is an expression  of
		  logical  pages  rather  than	physical sheets of paper. For example, if you are
		  printing two logical pages to a sheet, and you specified a range of 4, then two
		  sheets  of  paper would print, containing four page layouts. If you specified a
		  page range of 3-4, when requesting two logical pages to a sheet; then only page
		  3  and  page 4 layouts would print, and they would appear on one physical sheet
		  of paper.

       -r	  Do not reverse the pages in file.

EXAMPLES
       Example 1 Examples of postreverse.

       o select pages 1 to 100 from file and reverse the pages:

	 example% postreverse -o1-100 file

       To print four logical pages on each physical page and reverse all the pages:

	 example% postprint -n4 file | postreverse

       To produce a minimally conforming file from output generated by	dpost  without	reversing
       the pages:

	 example% dpost file | postreverse -r


EXIT STATUS
       The following exit values are returned:

       0	   Successful completion.

       non-zero    An error occurred.

NOTES
       No attempt has been made to deal with redefinitions of global variables or procedures.  If
       standard input is used, the input file will be read three times before being reversed.
