GNU find – search for files in a directory hierarchy

• https://manpages.debian.org/unstable/findutils/find.1.en.html

print each file’s last modification time (%T+) and its name (%P):

$ find . -type f -printf '%T+ %P\n'

Because the time stamp is printed first and also in a suitable way, this is what we use to sort the files within a directory by their last modification time.
