Sorry. Just had an error pointed out. Remove the i, not the g from the line
for case sensitity. Not thinking straight...
g is for global matches, so if your search string appears more than once on
each line of your input file, all instances will be converted to your
replacement string. If the g isn't there then only the first match on each
line will be replaced.

Subject: RE: String replace in a file
$lookfor = "string";
$replacewith = "newstring";
open IN, "input.txt" or die "Can't open input.txt: $!";
open OUT, ">output.txt" or die "Can't create output.txt";
while (<IN>) {
s/$lookfor/$replacewith/ig;
print OUT;
}
close OUT;
close IN;
output.txt should now have all instances of $lookfor replaced with
$replcaewith.
Note, it's case insensitive, if you don't want that, remove the g from
s/$lookfor/$replacewith/ig;
