Answer / guest
my $str="This is testing of string reverse";
print scalar reverse $s
chomp is used to remove the trailing new line.
If we give chomp list then it will remove the trailing new
line in all the elements of the list.
die function is used for handling the errors in Perl.
It terminates the program immediately after printing the
message passed to the die function.
die("testing of die");
It will print the message "testing of die" on screen and
terminates the program.

if($str=~/[0-9]{2}\.[0-9]{3}\.[0-9]{2}\.[0-9]{2}/)
{
print "Pattern $& get matched\n";
}
if($file1=~s/\/(.*)\/(.*)\.(.*)/$2/)

print "File Name is $file1\n";
}
print strftime("%B",0,0,0,11,2-1,2009);
