Re^3: directory exists by Fletch (Bishop) on Jun 03, 2005 at 02:53 UTC
Yup. Underneath it calls `stat(2)`, which would return `ENOENT` if it doesn't exist (file or directory). `-d` goes on to use the returned `struct stat*` to check if it's a directory or not. -- We're looking for people in ATL	[reply] [d/l]

Yes. I'd use a test like this in real code, and I guess it got into my recommendation: `is_dir { -e shift() ? -d _ ? 1 : 0 : undef; }` [download] With that I can test truth to see if there is a directory of that name, or defined to see if the name is in use. After Compline, Zaxo	[reply] [d/l]

Even that's redundant. The `-d` function by itself DWYM, and returns undef if the stat fails, false if the file exists but is not a directory.	[reply] [d/l]
