Home: Perl Programming Help: Beginner: -e and -s switches?

kicsihun New User Aug 19, 2009, 5:13 AM Post #1 of 4 (249 views) -e and -s switches? Can't Post Hi! I'm trying to understand a perl script. There are some switches (I guess) used, and I can't seem to find their role/use. The code looks like: my $filename ="doc"; my $filename1 = -s $filename; while( -e $filename && $filename1 == -s $filename ) What is the role or use of -e and -s? Thanks
