G'day perladdict,
You've been here long enough to know about using the strict and warnings pragmata. Why don't you? In this instance, warnings would have told you:
Use of uninitialized value $. in concatenation (.) or string at ...
You've also been here long enough to know about posting actual error and warning messages, not some vague or incomplete version. Here's what your code actually produces:
syntax error at -e line 2, near "if ==" (Might be a runaway multi-line "" string starting on line 1) Execution of -e aborted due to compilation errors.
Backticks (`...`) are interpolating quotes: see perlop: Quote-Like Operators. The $. is interpolated as an "uninitialized value" (which warnings tells you); so "if $.==" becomes "if ==" (which the full error message tells you).
That explains the problem; however, why are you starting another perl process? You're already running a perl process — just let it run the code.
