Re^2: How to handle metacharacters in input file for Perl one-liner code

Hello Dean,

Thanks for your reply.

I should probably have mentioned that I'm running this code inside an iterative loop, so am a bit concerned with execution time. I did consider going this approach instead of a system call, but honestly I have no idea which one would be a more cpu intensive process in terms of file open operations. Would you have any thoughts on that?

A pure Perl solution is likely to be faster than shelling out to the OS.	[reply]
