Thinking more about it, this is probably better done like this:

    
        [ -x "${dir:-/bin}/$1" ] && ret=0

Why? Well, /bin is probably in everybody's $PATH and using '.' would
sneak . into $PATH (well, not really but for the test if $PATH is
something like PATH=/bin:/sbin::/usr/bin) which is something *nobody*
wants.
