A:
All special variables used by Perl are documented in perldoc perlvar. You can access the version of this documentation that came with your perl
by entering perldoc perlvar
on the command line.

@KennyTM Apparently we posted essentially the same answer at the same time. So I deleted mine and put the extra info in it in your post so there aren't two substantially identical answers.

A:
All special variables used by Perl are documented in perldoc perlvar. You can view this document on your computer by running
perldoc perlvar
The documentation for a specific special variable can also be accessed at the command line using perldoc -v
:
perldoc -v @F
You may need to escape/quote some variables to avoid interpolation by your shell:
perldoc -v '$!'
or
perldoc -v "$!"
if you are using cmd.exe
.
For more information:
perldoc -h
perldoc perldoc
