Sort files with ls by last modified date and time.

By admin | Published 30/12/2013

The ls –help come with this args :
-t sort by modification time, newest first
You need to pass the -t option to the ls command to sort by time modified.

$ ls -lt

$ ls -lt

Also if you want to reverse the order of the sort then use -r option.

$ ls -ltr

$ ls -ltr

Let see one example:

$ ls -ltr *.py
Dec 30 18:16 test.py

1 2	$ ls -ltr *.py Dec 30 18:16 test.py

with iso time style

$ ls -ltr *.py --time-style=iso
12-30 18:16 test.py

1 2	$ ls -ltr *.py --time-style=iso 12-30 18:16 test.py

with full-iso time style

$ ls -ltr *.py --time-style=full-iso
2013-12-30 18:16:55.142174239 +0200 test.py

1 2	$ ls -ltr *.py --time-style=full-iso 2013-12-30 18:16:55.142174239 +0200 test.py

with long-iso time style

$ ls -ltr *.py --time-style=long-iso
2013-12-30 18:16 test.py

1 2	$ ls -ltr *.py --time-style=long-iso 2013-12-30 18:16 test.py
