This looks more or less like what I need, but I need some help parsing it. When I try to execute the command in the root directory, it says I don't have access, which is fair.
I think of the ">" symbol as "redirect output to a file, I'll tell you what the filename is". I think of "|" as "take this output and feed it into another program", which doesn't require a filename. I can tell that "2" and "1" represent stdout and stderr; is there a way to direct them both to the pipe, instead of the file? AFAIK, I/we don't have to first direct output to a file and then to grep, and in fact I don't know that it will work that way.

psmandup
PSMANDUP(1) FSF PSMANDUP(1)
NAME
psmandup - print duplex on non duplex printers
SYNOPSIS
psmandup FILE
DESCRIPTION
Tries to produce a version of the PostScript FILE to print in manual Duplex.
OPTIONS
-h, --help
display this help and exit
-v, --version
display version information and exit
-q, --quiet
don't print informational messages
-o, --output=FILE
save result in FILE. If FILE is `-', send to stdout
-n, --no-fix
don't call fixps to fix PS problems in FILE
-f, --front
output only the front pages (recto) on the regular tray
-b, --back
output only the back pages (verso) on the manual feed tray
Produced output is meant for PS level 2 printers which don't support Duplex printing, but support Manual Feed. Once the first set of pages
is printed (odd pages), manual feed is asked: introduce the odd pages to print the even pages on the other side.
Because there is usually a short time out for manually fed jobs, you should really be next to the printer. If ever the time out expired,
use the option -b to send only the missing part.
Environment variables FIXPS, PSSELECT and PSSET, if defined, are used to find the tools.
