The following message is a courtesy copy of an article
that has been posted to comp.unix.shell as well.

Currently if one wants the _full path_ of the latest file
of a directory other than the current one, then
f=`ls -t ~/.procmail/bitbucket|sed q`
will not do.
One must do f=`ls -t ~/.procmail/bitbucket/*|sed q`
which is a big waste in the shell and might even exceed some
argument limits. Or, one must dance around:
a=~/.procmail/bitbucket/
x=`ls -t $a|sed q`
f=$a/$x
all because ls has no switch to make it output the directory it was
given.

Jim> find /tmp -printf '%T@ %TY-%Tm-%Td ... %p\n' | sort -nr
my goodness, that is pulling out all the stops...
Hmm,
f=`find ~/.procmail/bitbucket -type f -printf '%T@ %p\n'|
sort -nr|awk '{print $2;exit}'`
was as efficient as I could make Jim's solution.
Anyways what I want to do is
f=`ls -t --dont-strip-path-I-was-given ~/.procmail/bitbucket|sed q`
i.e. getting the full path of the latest file there, just using ls and
sed, without the above "more involved" workarounds.
Anyways, I hope I have show the "reasonable case" for adding one more
option to the venerable ls command.
