perl regexp problem 2

I have a list of command to parse...


> ls -lart 
> ls 
> ls /etc/passwd 
> ping 
> ping
> LS

I have to count the number of times ls and ping was executed, I have to not count uppercase variant like LS and PING, but I have to count command launch with option like "ls -lart"

How to check if a line contain the exact word ls or ping or whatever?

With regular expression!!!



my $count = 0;

while (<STDIN>) {
  $count++ if $1;
