ben@strontium:~$ echo `ls \`pwd\``
.ICEauthority .KillLog .MsgLog .Xauthority .Xresources [snip]

oh yes it can. :-) Of course, the $() form would be clearer, i.e. echo
$(ls $(pwd)), especially with more than one level of nesting (which I've
never even attempted).

hmm.. if the output is like "4 Fri 21 Jan 2000 00:15:59 GMT" as you say,
then how about

DATA=`awk whatever`
set -- $DATA
NUM=$1
shift; DATE="$*"

would that work?
