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

In order to run ll with sudo, the user that is sudo'ed (superuser or another user, as specified by the security policy) needs an alias ll='ls -al' in his profile.

Note that even if defined, you may not be allowed to execute it by the security policy. To find out which commands you may execute type sudo -l

Answer 2

I am quite late, but ... In Debian 10 the command ll is commented (#).

To make ll available just change yourr .bashrc file:

su gedit .bashrc

After in your text editor uncommnet as you wish:

# some more ls aliases alias ll='ls -l' #alias la='ls -lA'

Do not forget to restart your terminal emulator.

Answer 3

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

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

  • whatis <command_name> 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.

Answer 4

Try sudo ls -l.

As ll is a shorthand for ls -l.

Answer 5

Create an alias for ll.

alias ll="ls -al"

Answer 6

That's expected because ll is defined in your profile (.bashrc in Ubuntu, for instance).

grep "alias ll" ~/.bashrc
alias ll='ls -alF'

Your .bashrc will not run when you sudo.
