Hi Pawan. What you need is backtick quotes: `ls` or qx(ls) which is the same thing. It does the same as system in that it executes a shell command, but instead of the exit status it returns the text that the command output to its STDOUT. In list context the return value will be a list of lines (still with their trailing newlines) and in scalar context it will be a single scalar value containing all of the output. Be careful though: it's usually better to write Perl code than to rely on the output from an an external utility.
