file io - Bash scripting: Deleting the oldest directory

Question

I want to look for the oldest directory (inside a directory), and delete it. I am using the following:

rm -R $(ls -1t | tail -1)

ls -1t | tail -1 does indeed gives me the oldest directory, the the problem is that it is not deleting the directory, and that it also list files.

How could I please fix that?

Answer 1

rm -R "$(find . -maxdepth 1 -type d -printf '%T@%p
' | sort -r | tail -n 1 | sed 's/[0-9]*.[0-9]*//')"

This works also with directory whose name contains spaces, tabs or starts with a "-".
