I'm trying to use grep to compare a directory path such as C:\apps\c++\application with an array of certain file types (e.g. .cpp, .hpp etc) residing on the hard drive, some of which are in the C:\apps\c++\application directory.

The line:
@fileList = grep{/$dirPath/} @allFiles;
works for directories which do not have the plus symbol in their path but not for ones which do. I've tried escaping the plus characters so in effect it's doing:

grep {/c:/apps/c\+\+/application/} c:/apps/c++/application/myfile.cpp

but none of the files in the C++ directory are being returned and if I unescape the "+" I get an error saying "nested quanitfiers in regex"

Any help would be greatly appreciated

Thanks
Steve
