In unix environment need csh or ksh script that will mangae directory of files.  Only need the latest 10 log files, thus need script that removes the oldest file.

Display all file ending on ".log", ordered with oldest last, filter out
all but the last one:
# ls -t *.log | tail -1
Now, use the command from above and take it's output as the
argument for remove command
# rm -f `ls -t *.log | tail -1`

Tintin,
as far as I can see, he wanted to get "the oldest" file deleted.

Your solution deletes all but the first ten files. Your solution is
much more enhanced and quite elegant -- but unfortunately
seems a bit overcrafted for the original Q.
