How to find command line program with which
Try this:

for i in `echo $PATH | sed 's/:/ /g'`; do
    printf "\033[1;103;30m        $i\033[0m\n"
    ls "$i" | grep "ur_setup"
done


This will iterate through directories included in PATH, print them in yellow and then if there's something in there matching ur_setup pattern, print it. It can be done cleaner, but it's not worth creating a big function for a small need.

Also, if there's no result from which ur_setup (neither not found nor like /usr/bin/spiderd), you should try type which.
