Hello tkguifan,

To determine the platform on which the script is running, you can use either the built-in variable $^O (also spelled $OSNAME; see perlvar#General-Variables) or $Config{osname} from Config. See the recent thread Cross-platform accented character file names sorting, which also discusses the correct syntax for using the if pragma.

To test whether or not a module is present in the system, use or require it in an eval and then immediately test the value of $@:

22:42 >perl -wE "eval qq[use Unknown;]; say $@ ? 'failed' : 'succeeded
+';"
failed

22:43 >perl -wE "eval qq[use Data::Dump;]; say $@ ? 'failed' : 'succee
+ded';"
succeeded

22:56 >

Hope that helps,
