That regexp shouldn't have the $ escaped. That makes it
search for the literal string '$name', not the value of $name.
Try this:
if (/^$name$/i) {
You may want to quote any meta-characters in the name:
if (/^\Q$name\E$/i) {
Your other, bigger problem, as
cds pointed out, is
that you're only searching the first line. If the match isn't in
the first line, you then ask whether or not to add the name.
You'll want to fix this.
My suggestion, in fact, would be to use a DBM file. DB_File,
perhaps.
