I had some files with a date in it:
some file 23.05.2017.abc some file 23.05.2007.abc some file 15.07.2017.abc some file 02.12.2008.abc
To sort them, use the
KEYDEF feature of
find . | sort -k3.8d -k 3.6d -k 3.5d
It it also good to use the
--debug option of
sort, as it will show you where sort found the key.
