Test for if statement in Perl

This will be super-elementary for the Perl gurus I know frequent the forums. What is this if statement doing? I'm guessing it tests if a directory is empty, but I have been totally ineffective finding documentation online regarding the test parameters for if statements?

if (-e "/var/adm/checkperms")

-e => existence of a file

Hmm... Interesting. That doesn't make much sense in the context of the script I'm looking at, but it wouldn't be the first time that's happened. Thanks.

Oh, these operators are described in the perlfunc man page and to save you a little time digging through all the pages do:
man perlfunc
/-X EXPR
that search will put you in the neighborhood.
