Linux command 'll' is not working

Question

I am able to run ll command with my user but not with sudo, it giving me error as command not found!

Answer 1

As it has been explained:

ll is actually an alias to ls -l

In your prompt, I would recommend using the following 3 commands when you are not sure about a command that you input:

• type will give you information about the command, in our particular case, the output will be: ll is aliased to 'ls -l'

  • which will show you the path of the command you are going to use

  • whatis will give you basic information about the command

Last but not least, alias ll="ls -al" will allow you to create the alias you are looking for. However to avoid redefining your aliases every single time you open a new shell. You will have to save them in your .profile or add them in your .bashrc file (use .bash_aliases file for this purpose and uncomment that section in your .bashrc ) in the home directory of your user.
