That is not Perl. The membrane-thin wrapper of Perl serves literally no purpose. That is nothing but shell code. If you write the loop inside shell you'll save so much trouble and CPU time.
I too made this error when first learning to program in Perl and shell. Learn a little more shell and it will make more sense.
You can also split across multiple lines for readability by putting backslash-newline wherever you need to split it.
Remove the echo once you've tested and made sure it does what you want.
