You need to quote your arguments (and check how you spell "argument", wink wink) -- that should solve several of your problems.
Single quotes will prevent the expansion of $2 into its value; you are then grepping literally for (end of line) 2 which will never match. (Remember $ means end of line in regular expressions.) So don't use single quotes around a variable.
Things get tricky when you want to use both single quotes and double quotes, but you can even mix them in the same string. So to grep for $2 at end of line you could do something like
That's $2 in double quotes, and $ in single quotes, without any space or anything in between. (Next week, we will look at double quotes in single quotes and single quotes in double quotes in the same string.)
What's with the perl? This is a shell script, you'd run it with sh, not perl (although I guess perl is always Doing What You Mean and will actually run sh for you if it sees that you are giving it a shell script; but that sounds rather fragile for you to rely on).
