Printing a file using Shell Script in Unix env called from a Java Application

[karthik Suryanarayanan]

Hi Guys,
I'm using a Java application which runs a shell script in Unix server for printing . In shell script I want to set the page length and remove the file if print was successful. My code is as follows .

 pr -t -l34 "$1" | lpr
 OUT=$?
 if[$OUT -eq 0];then
 rm $1

I have tried with

 pr -t -l34 "$1" | lpr -r 

but here file is not getting deleted after printing. Hence i went for using if / else .

My question is if any exception occurs in shell script(OUT returns value other than 0) , how to return that value to my calling program in Java .

pr -t -l34 "$1" | lpr && rm "$1"

The quotes on rm are for consistency, and like the quotes on the pr command, mainly server to ensure that filenames with spaces and other such artifacts are properly parsed.

Technically, this only detects whether the format and spool were successful. But once lpr hands off to the spooler, that's usually considered sufficient.
