#!/usr/bin/perl -l $zipadidoda = 'le12 ogx'; print "In: $zipadidoda"; if( $zipadidoda =~ s/^([A-Z]{1,2}\d{1,2}[A-Z]?)\s?(O|\d)([A-Z]{2})$/uc +("$1 ".(0+$2).$3)/ie ) { print "Out: $zipadidoda"; } else { print "Invalid zipcode"; }

You wanted a single re, so you got one!

Or is the 'e' modified considered cheating?

:)

Update: removed redundant quotes

Update: and fixed the space after a tip from ww

    A cheat that lets you avoid the /e cheat:
    s/^([A-Z]{1,2}\d{1,2}[A-Z]?)\s?(O|\d)([A-Z]{2})$/\U$1 ${\(0+$2)}$3/i

    Gilimanjaro: your regex strips the space between segment_one and the last_three, if one exists, whereas OP sought to insert one, if there was no space before \d[A-Za-z]{2}
      You're right! Fixed in an update...
