Answer 1

little off-topic - but anyway. only useful when working within filetrees

ls -l -r --sort=time

from this you could create a one-liner which for example deletes the oldest backup in town.

ls -l -r --sort=time | grep backup | head -n1 | while read line; do oldbackup=\`echo $line | awk '{print$8}'\`; rm $oldbackup; done;
