My take is that the ls command is already so heavily loaded with options that
you're better off rolling your own. For example, let's beuild two new
commands. lsd and lsD. lsd will only list directories and lsD will only list
nondirectories.
lsD ()
{
typeset args1="$1"
typeset args2="$2"
ls -la $args1 | awk '!/^d/ {print $9}' | xargs ls $args2
}
Now you can try things like
lsd '-d x*' -l
and lsd is left as an exercise for the student. ;-)
