Hi and how do I address you correctly:
Smoot or Carl-Mitchell ?

Thanks a lot for your efforts and explanations !
Yes, ls -a showed me that single file with a "dot = hidden" !! ;-)

That overlooked "dot", a first time experience for me, and especially
"lock" 
at the end of the file name irritated me !!!

I assumed that, with lock, the file may have a special thumb to keep it
(b)lock(ed) !?

Later, with some more experiments, I was able to remove properly
myself. ;-D

Thank you and cheers, svobi
