I think you are over-escaping the shell.

Since you are in single-quotes, attempting to escape the $ using \$ causes the $ to be interpreted literally by perl where you did not intend.

Specifically, I think you intended perl to see "$var" , but you have a "\" preceding the $ , and that \ is passed to perl, so perl thinks you want a literal $var, instead of interpolating.

Here is how perl currently sees your re: 

  s#\Q(.*)\$/',\$lines,\$matches))10.(.*)\$/',\$lines,\$matches))(.*)\
+$/',\$lines,\$matches))# #gi

You need to remove all attempts to escape all $'s in front of variable names.

Update:The problem is that \Q interpolates and disallows \$ - see my response below.
