Perl from USB pen to run on both linux and windows

[G182]

Hey guys,

Im somewhat new at perl and was wondering if there was a way to run a perl script or tool made from perl, from a USB pen that would work both on Linux and on Windows?

Thank you

Any help would be greatly appreciated.

short answer:
Yes, the Perl interpreter is platform specific, but the Perl code is (or -can- be) platform independent.

There are some caveats. Specifically file paths are different.
However, Perl does understand the following are equivalent.

my $path = 'C:\foo\bar\';
my $path = 'C:/foo/bar/';

I do believe that file paths are not case sensitive, tho I am unable to test this at this time.

the windows shbang line looks different

#!C:/perl/perl.exe

but if you invoke the program through Perl from the CLI.
e.g.:

perl foo.pl

shbang doesn't matter.

Also, you can't use linux system commands on a windows box, and vice versa. Stick to the Perl library.
