Not a perfect equivalent. On Linux, ls -lF /proc/self/fd shows the contents as symlinks, which is handy since you can just read the links to see what they're pointing to. On OSX, ls -lF /dev/fd shows three ttys and two directories. Though I also note that on my Ubuntu Trusty system, /dev/fd is itself a symlink to /proc/self/fd.
