utterlyconfused has asked for the wisdom of the Perl Monks concerning the following question:

Hi Perlmonks,

I'm new to perl and I have an exam coming up. Trying to
figure out the meaning of certain special variables, in this
case $/. I just want to confirm if I understand it right.
Does it convert a multiline string into a single
string?

Thanks

    No. See perlvar. It influences what Perl considers a "line" when reading a file using the diamond operator ( <$fh> ). It does not magically transform data already read into memory into different things.

    Google Perl cheat-sheet, pick one(or a dozen), print it out and keep it handy. At some point you won't need it, save the PDF file and discard the paper...

    --hsm
