How to use ls sort by date in linux/unix

Ls sorted by date, which makes it easier for us to manage files and subdirectories, especially when there are many files or directories.

Linux ls -t option can be sorted by date from newest to oldest, or ls -rt option can be sorted by date from oldest to new.

  • ls -t sort by time modified
  • ls -r reverse the order

# ls sort by date from newest to oldest
➜ ls -t

# ls sort by date from oldest to new
➜ ls -tr
ls sort by date

However, you will find that although the above method can be sorted by date, it is not easy for us to view. At this time, we usually use it with ls -l option, which can display richer structured information.

  • ls -l list in long format
➜  ls -lt


➜  ls -lrt

ls sort by date

When the number of files and subdirectories in a directory is large, we recommend using the ls -rlt long format to sort by date, which will allow you to find newer files or directories faster.
