Perl

perl(1) is a scripting language for Unix systems. It borrowed and built upon the syntax of Unix tools like ed and awk, and in turn inspired the PCRE (Perl Compatible Regular Expressions) and PCRE2 libraries.

This article refers to Perl 5, not raku.

Example

print "Hello, World!\n";

Execute this file by running:

perl hello.pl

perl(1) is better known for its powerful yet obfuscated syntax, especially in the spirit of Bash one-liners.

perl <<<'print join " ", reverse split " ", "hacker, Perl another Just"'

Or more humorously:

perl <<<'$_="krJhruaesrltre c a cnP,ohet";$_.=$1,print$2while s/(..)(.)//;'
