Your solution with a for loop has the word perl within it. Is this a script in a language other than perl, or is there some significance to the use of "perl -pi.bak"? I'm not familiar with cygwin - the last time I tried to install it something didn't work right. Regards, Scott	[reply]

Is this a script in a language other than perl It's a Windows shell (`cmd`) command. If you need it in a batch file, you need to escape the `%`. Change `%q` to `%%q`. I'm not familiar with cygwin Cygwin is a OS emulator, not a shell or a scripting language. When people say Cygwin, they usually refer to `bash` and/or GNU tools. samtregar showed that a solution can be obtained using `bash` and GNU tools. I showed that such tools weren't required. is there some significance to the use of "perl -pi.bak" It invokes `perl`. `-p` and `-i` are documented in perlrun.	[reply] [d/l] [select]
