Welcome young_monk_love_perl,

On *nix try this at the command prompt: 

perl -e '$v=qx/ls/;open $f,">","./file";print $f $v;'

[download]

What this one liner does is ask the system to list the files in the current directory and save in variable '$v'; opens a file(./file); and print the contents of variable '$v' to the file. You can use an editor to view the contents of the file.

That's a rough beginning, but Perl has so much more to offer -- so enjoy!

Regards...Ed
