Well I certainly is a fan of locate, in this case it partly failed because 'locate cups' has more than 1000 entries and rolls off the konsole buffer and anything 'bin' is long gone, actually in my case I am down to 'usr....' on the first line so I never got the 'bin' association, this might have triggered my brain.
The clue was cupsd, which I ought to have remembered, I know it, though I was getting a bit agitated over not getting anywhere.
Just for the fun, here is the suggested result, and you are right there is a couple of interest to me here. I guess you know where 'cupsd' is, but it would have been nice if it had shown up here too.
[root@localhost /]# locate /bin/cups
I am back on track.
Thanks for post, I will remember the 'bin' next time, hopefully. Everytime I think I am doing really well now, I get one of those items to keep me in line.
