Well, I guess that you don't *have* to remove the files, but it's not hard to do. First of all, Perl has a system() call, similar to C's. So, for example, say if you have the names of your temp files in a list called @temp_files, you could do: foreach $temp_file (@temp_files) { system ("rm $temp_file"); } A better solution (in my opinion) would be to use Perl's built-in unlink() function, which again, is similar to C's. Interestingly, almost all of C's system-like calls are also in Perl. Anyway, you could do something like this: foreach $temp_file (@temp_files) { unlink $temp_file; } Or more concisely, just this: unlink @temp_files; And then again, if the names of the files all end with a certain extension, for example, .TEMP, you could do something like this: unlink <*.TEMP>; Take your pick... :-) -- Elton
