Hi,
If I'm calling the diff program from within a Perl script with something
like:
system("diff file1.txt file2.txt");
how can I detect if there is a result or not, since if the files are
identical, diff
doesn't have any output? I need to be able to be able to determine if there
was any output from within my script so that I can take one particular
action if diff
returned something (the files were different) or take another if diff didn't
return anything (the files were identical). Thanks for all help with this.
-Jose
