What does it mean "$_." in PERLby anakin30 (Acolyte)
|on Aug 25, 2010 at 00:56 UTC||Need Help??|
anakin30 has asked for the
wisdom of the Perl Monks concerning the following question:
I'm new to perl and i'm going through the lesson online
i'm now going through module 10 - Regular Expressions, and i saw the line below
m/PATTERN/ --> This operator returns true if PATTERN is found in $_.
I need someone explain to me what does it means "$_." and how does it work in the perl code?
Does it means "this" in perl?
Thank You Guys
