Does any one can explain this IF condition in a high level explanation

$LFB='(RMK\s|HTG\s|MWS\d|HML\s|ACC\s|INT\s|SLA\s|D PA\s|MW\d\s|SA\s|CKL\s|SN\s|SUS\s|CPG\s|TSC\s|OCL\ s|PRI\s|BG\s|TRC\s|TGP\s|DNP\s)';


if (/^(\s{2}|)([A-Z]|)$LFB\s{0,2}([\w\W]+.*\S{1}|\s{44})(\s*)$/)



Thanks in advance,

Ricky

That takes the value of $LFB and uses it as part of the regex. I'm not all that great with regexes so I won't spend time trying to trace it out. If you want more details you can take a look at a couple of the Perl rexex tutorials:

perlrequick: http://perldoc.perl.org/perlrequick.html
perlretut: http://perldoc.perl.org/perlretut.html

perlre: http://perldoc.perl.org/perlre.html
perlreref: http://perldoc.perl.org/perlreref.html

This particular section will be very handy:
