Thanks. Somebody else tried:
found=`which "$command"`
if test -n "$found"
then
... use $found as the full path to the command
fi
and got burned because "no httpd in ..." comes to the stdout!
I did not exactly recall if there was an issue with the exit
status, but your demonstration shows that the status is also
useless.
We _could_ do something ugly and pointless like:
test -f `which "$command"`
but I'd say I prefer the alternative I sent out at that point.
