Question String Compare
I have a string
$string1 = "4PL400".

Now i read a string from <STDIN>.....

now i can enter both 4pl400 and 4PL400.......the question is how do i compare the input to string1.

In clear words, the input is case insensitive....but the comparison has to be done..

Please help and advise

Thanks in advance

Use the "lc" operator to change both strings to the same case, then compare with "eq".

You do do a case insensitive regular expression match.

Code:
$string1 = "4PL400";

$string2 = "4pl400";

if ( $string2 =~ /^$string1$/i )
{
  print "Matched!\n";
}
else {
  print "No match :(\n";
}
