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

== 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. As an example (credit to [[https://groups.google.com/g/comp.lang.perl.misc/c/nK-lswsaMec/m/DBL87v4FxOwJ|Randal L. Schwartz]]):

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

Or more humorously (credit to [[https://www.cpan.org/misc/japh|Raymond Chen]]):

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