One or two suggestions:

#!/usr/bin/perl 
use warnings;
use strict;
my $found = 0;
my $line = 0;

while (1) {
    system("clear");
    print "Enter P to process a file or Q to quit: ";
    chomp( my $ans=<STDIN> );

    if ( $ans =~ /^p$/i ) {
        print "What file would you look to open? ";
        chomp( my $file=<STDIN> );
        
        die "Could not open file: $file!\n\n" if !-e $file; 
        
        open(my $fh, '<', $file);

        print "What text would you like to search for? ";
        chomp( my $find=<STDIN> );

        print "What text would you like it replaced with? ";
        chomp( my $replace=<STDIN> );

        open (NEW, ">", "new.txt");
        while ( <$fh> ) 
            {
                if ($_ =~ /$find/i ) 
                    {
                        $line = $_; 
                        $line =~ s/$find/$replace/g; 
                        print NEW "$line";
                        $found += 1;
                    }
                else
                    {
                        print NEW "$_";    
                    }   
            }
        print STDERR "\nFound and replaced $found copies of \"$find\" 
+with \"$replace\".\n" if $found > 0;
        print STDERR "\n$found copies of \"$find\" found in $file.\n" 
+if $found == 0;
        unlink "new.txt" if $found == 0;
        
        sleep (5);
    }
    elsif ( $ans =~ /^Q$/ ) {
        exit();
    }
    
    
    close NEW;
    $found = 0;
    
}

Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Please read these before you post! —
