It's the concatenation operator:

  my $greeting = "Hello";
  print $greeting . " world!\n";

Often you can use variable interpolation (ie

  print "$greeting world\n";

but there's many times you don't want to.

I'd recommend a copy of "Learning Perl" by Schwartz and
Phoenix, as the publishers say:

   Learning Perl is the quintessential tutorial for the Perl
   programming language. The third edition has not only been
   updated to Perl Version 5.6, but has also been rewritten
   from the ground up to reflect the needs of programmers
   learning Perl today. Other books may teach you to program
   in Perl, but this book will turn you into a Perl
   programmer
