postreverse(1) User Commands postreverse(1)NAMEpostreverse - reverse the page order in a PostScript file
SYNOPSISpostreverse [-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 com‐
ment, 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 contains single numbers N and ranges N1 − N2.
A missing N1 means the lowest numbered page, a missing N2
means the highest. The page range is an expression of logi‐
cal 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.

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.
