what if...what if someone were to use up another option letter for ls
and allow the user to specify a "format" (sort in the same way that
date and ps allow user specified formatting)? hmm...-O looks unused. :)

i wrote one once so that i could see more stuff. then i wrote another
today because i read this thread. then i realized i could emulate my
old script using my new one, and even ls (ls -lfdT actually, with -F
and -L as options, and perhaps without -T).

a reasonable formatting grammar could do that also. to use myself as
% stat stat
6 164676 100755 1 204 20 669392 5908 1009604500 1009604399 1009604399 8192 12 stat
% stat -f "set atime=%at;set ctime=%ct;set mtime=%mt" stat
set atime=1009604407;set ctime=1009604399;set mtime=1009604399
% eval `./stat -f "set atime=%at;set ctime=%ct;set mtime=%mt" stat`
% echo $mtime $ctime $atime
1009604399 1009604399 1009604425
admittedly, i wrote it in perl (so i don't get all the struct stat
fields), and the format parser is "crude", but it works well enough to
make me happy.
