pl

We have hosted the application pl in order to run this application in our online workstations with Wine or directly.

Quick description about pl:

Some tasks are too menial for a dedicated script but still too cumbersome even with the many neat one-liner options of "perl -E". This small script fills the gap: various one-letter commands & magic variables (with meaningful aliases too) and more nifty loop options take Perl programming to the command line. Fully imports List: : Util. With no program on the command line, starts a pl Shell.

How to "e(cho)" values, including from "@A(RGV)", with single "$q(uote)" & double "$Q(uote)". Same for hard-to-print values:
$� pl� 'e� "${q}Perl$q",� "$Q@A$Q"'� one-liner
$� pl� 'e� \"Perl",� \@A,� undef'� one-liner

Loop over args, printing each with line ending.� And same, SHOUTING:
$� pl� -opl� ''� Perl� one-liner
$� pl� -opl� '$_� =� uc'� Perl� one-liner

Print up to 3 matching lines, resetting count (and "$.") for each file:
$� pl� -rP3� '/Perl.*one.*liner/'� file*

Count hits in magic statistics hash "%N(UMBER)":
$� pl� -n� '++$N{$1}� while� /(Perl|one|liner)/g'� file*.
