It can be useful on a Linux server to sort all of the files in a directory by date. Sometimes you may want to backup files older than a certain date or you may just want to see what is in a directory and what date those files were created. Use the information below to list all of the files in a directory sorted by date.

Above you can see that the files are listed newest files first. If you need to list the files in the directory with the oldest files first you can simply add the -r switch to sort the files in reverse as shown in the below example.
