Linux notes (3) sudo

just installed Ubuntu, appearing on the first line of the terminal: to run a command as administrator (user "root") with "sudo <command>".

See "Mans Sudo_root" Fordetails

Translated:

Run a command as an administrator (the "root" of the user), using "sudo < commands >

See "Man sudo_root" for more information

In other words, if you want to run the "ls" command, you can enter "sudo ls" on the command line,
Then you will be prompted to enter the password, then you enter the password, and then return to the line.
But if you want to keep the superuser (that is, root, the equivalent of an administrator), you can execute "sudo-s" and then enter the password, and you will be able to execute the command as a superuser without having to add "sudo" in front of each command.
