The ls command is used to display directory contents in the Linux terminal. By default, the output is sorted alphabetically. However, you might sometimes need to display the contents in reverse order. This can be done using the ls command itself or by piping the output to an external program like sort.
While ls has built-in sorting capabilities and is highly compatible with other ls options, the sort command is a dedicated external program that offers its own advantages for sorting output that you can use.
Steps to list directory content in reverse in Linux:
- Open the terminal.
- Display directory contents using the ls command.
$ ls Applications Documents Dropbox Movies Pictures System tmp Desktop Downloads Library Music Public Workspace
- Pipe the ls command output to the 'sort' command to show the results in reverse order.
$ ls | sort -r tmp Workspace System Public Pictures Music Movies Library Dropbox Downloads Documents Desktop Applications
- Directly display directory contents in reverse order using the ls command.
$ ls -r tmp System Pictures Movies Dropbox Documents Applications Workspace Public Music Library Downloads Desktop
- Show directory contents based on access time or other criteria.
