You get something that looks like

kithrup 10> ls -l /dev/fd
total 0
crw-rw-rw- 5 bin	bin	46,0	Jun 11 15:48 0
crw-rw-rw- 5 bin	bin	46,1	Jun 11 15:48 1
crw-rw-rw- 2 bin	bin	46,2	Jun 11 15:48 2
crw-rw-rw- 1 bin	bin	46,3	Jun 11 15:48 3
crw-rw-rw- 1 bin	bin	46,4	Jun 11 15:48 4
crw-rw-rw- 1 bin	bin	46,5	Jun 11 15:48 5

And so on.  They are normal device drivers; stat'ing them doesn't do
anything strange, just opening them.

(/dev/stdin.o, /dev/stdin.s, /dev/stdin.c, /dev/stdin, and /dev/fd/0 are all
linked on my system; similarly with /dev/stdout.  /dev/stderr is linked to
/dev/fd/0, and all the others [through 60 on my system] only have one link.)
