(Ovid) Re(3): path is broken

Perl keeps track of the line number of the file you are in so you don't have to:

perl -e "while(<>){};print $." somefile.txt

Gotta love that $. variable :)

I particularly like this code, posted by Abigail on (I believe) comp.lang.perl.misc: `perl -wlpe '}{_=.}{' <file>` [download]	[reply] [d/l]

There's a lot of $. (<-- that dot is a regex =]) variables to love, yet I've only stumbled across a few of them, and even less explanations of what those variables do. Anyone know of a comprehensive listing of what variables are available to us in the $/./ (<-- that is a correct regex!) format and what they all do? I haven't noticed it in any of my books (I haven't read all of every book yet, so standard disclaimer of "i may be a fool" applies here). -marius	[reply]

As merlyn is not around I will have to sub and give you the ob. reference: `perldoc perlvar` will give you the entire list.	[reply] [d/l]
