If you have created a temporary alias by using the alias command, you can use the unalias command to remove it.

For example, let’s set a temporary alias:

$ alias docs='cd /home/linuxconfig/Documents'

Now, to remove this alias, we would execute:

$ unalias docs

You can verify that the alias has been removed by trying to use it, or by checking the list of configured aliases on your system:

$ alias -p

How to remove permanent alias on Linux

If you have created a permanent alias by editing the ~/.bashrc file, you just need to open this file and remove the corresponding line.

  1. You can open the file with nano or your preferred text editor.
    $ nano ~/.bashrc
    
  2. In this file, locate the alias that you wish to remove. Simply backspace the line to delete it completely.
    The .bashrc file contains the permanent alias we wish to remove
    The .bashrc file contains the permanent alias we wish to remove
  3. When done, save your changes to the file and exit it. Then, execute the following command to make the changes take effect:
    $ source ~/.bashrc
    
  4. You can verify that the alias has been removed by trying to use it, or by checking the list of configured aliases on your system:
    $ alias -p
    

Closing Thoughts




In this tutorial, we saw how to remove an alias on a Linux system. The steps to remove a temporary alias versus a permanent alias are different, but are easy enough to do for any user. You may use the alias command again in the future to create another temporary alias, or edit the ~/.bashrc file to create a permanent variable that persists after subsequent reboots.
