Most likely, shell quoting was tripping up your oneliners.

In most shells, double quotes interpolate variables. As you put your Perl oneliner in between double quotes, all the dollar signs were expanded to (empty) variables. You were unlucky in the sense that your program seems to have remained valid Perl even with all variables removed.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
