Question

Make a program that prints each line of its input that mentions fred. (It shouldn’t do anything for other lines of input.) Does it match if your input string is Fred, frederick, or Alfred? Make a small text file with a few lines mentioning "fred flintstone" and his friends, then use that file as input to this program and the ones later in this section.

Explanation:

This assume that input is a file and is given on command line. Please note this will ot print lines with frederick as thats what I feel question is asking for

#!/usr/bin/perl -w

open(FILE, $ARGV[0]) or die("Could not open the file $ARGV[0]");

while ($line = <FILE>){

if($line=~/\s+fred\s+/)

{

print $line;

}

}

close(FILE);
