in reply to grep for windows

Just adding a point of interest - RonW and Athanasius explain how to avoid the Leaning toothpick syndrome, which is also mentioned in perlop:

... you can use any pair of non-whitespace (ASCII) characters as delimiters. This is particularly useful for matching path names that contain "/" , to avoid LTS (leaning toothpick syndrome).

        ...it is unhealthy to remain near things that are in the process of blowing up.     man page for WARP, by Larry Wall
