Specifically, note that ll alone shows a file 255 linked to /dev/pts/8, but ll /dev/fd/ shows instead a file 3 linked to /proc/24334/fd. (The proc number changes each time; I suspect it to be the process number of ll itself.) ...I also note, now, that the dates are different - am I getting a different directory for . than for /dev/fd/? I further note that I can't create a file in /dev/fd (with either path).
