Replace command output with custom error message












0















I have been trying to change the output of ls without changing permissions. When the user writes ls, I want to print some kind of error like command not found.



I tried doing this with an alias but it's not working.



alias ls=error >> ~/.bashrc

          Add this line to your ~/.bashrc file:



          alias ls="echo sorry ls command not found"


          You can do that simply with echo:



          echo 'alias ls="echo sorry ls command not found"' >>~/.bashrc


          Every newly opened terminal will now print your error message when you run ls:



          $ ls
          sorry ls command not found


          If you want to call the actual ls, use one of the following approaches to bypass the alias:



          /bin/ls
          ls
          command ls
