You can use the special variable `$^O` to see what your script is running upon: `#!/usr/bin/perl -w use strict; print "This is : $^O \n"; if ( $^O =~ /win/i ) { print "Looks like Windows\n"; } if ( $^O =~ /linux/i ) { print "Looks like Linux\n"; }` [download] (Note: That is "capital o", not "zero".)

And in the future, you can find answers to questions such as this with "perldoc -q", e.g. `perldoc -q 'operating system'`.	[reply] [d/l]
