If you check the “keep password” option in KdeSu, you will only have to type the root password once per login session. Type kdesu -c 'command -option argument'Īnd enter the root password, or type kdesudo -c 'command -option argument'Īnd enter your password (if authorized to run sudo). They allow you to run X Window programs as root with no hassle. Kdesu and kdesudo are graphical front-ends to su and sudo respectively. KdeSu, KdeSudo (preferred when using KDE) Be aware that while this works in most cases, it does not work universally. Simply prefix your desired command with the command pkexec. The command must have been allowed by the system administrator. Super lets you run commands as another user, including root. This not a full-blown tool to run arbitrary commands: you type op followed by a mnemonic configured by the system administrator to run a specific command. Op lets you run commands as another user, including root. Calife is more light-weight than sudo but also less configurable. It is similar to the much more widespread sudo (see above). Other programs CalifeĬalife lets you run commands as another user by typing your own password, if authorized. Notably, systemd-based systems will prompt you for the root password when you boot this way. On many systems booting into single user mode will give the user access to a root shell without prompting for a password.

You can also get to single user mode by using the telinit command: telinit 1 however, this command requires you to already have gotten root privileges via some other method in order to run. Typically, this is the smallest number of services required to have a usable system. Rather, the system will only start the services defined for run-level 1. Note that booting into single-user mode is not the same as booting the system normally and logging in as root. You can boot into single user mode by passing single or emergency on the kernel command line. This is intended primarily for emergency maintenance situations where booting into a multi-user run-level is not possible. Single user mode, or run-level 1, also gives you root privileges. Logging in directly as root is mainly useful in emergency situations, such as disk failures or when you've locked yourself out of your account.

Be very careful, and avoid running complex applications as root as they might do something you didn't intend. If there is a root password set and you are in possession of it, you can simply type root at the login prompt and enter the root password. (The point is to limit the damage if the root password is accidentally leaked to someone.) Logging in as root On some systems, you need to be in group number 0 (called wheel) to use su. To run multiple commands as root, it is more convenient to start an interactive shell. Note that you need quotes so that the command is not parsed by your shell, but passed intact to the root shell that su runs. The command to run must be passed using the -c option. When run with no user specified, su will default to the root account. It lets you run a command as another user, provided you know that user's password. The su command exists on most unix-like systems. Read the sudoers man page for more information use sudo visudo to edit the sudoers file. Sudo is very configurable for example it can be configured to let a certain user only execute certain commands as root. The difference is that -i re initializes the environment to sane defaults, whereas -s uses your configuration files for better or for worse.įor more information, see the sudo website, or type man sudo on your system. Sometimes, it is more convenient to run an interactive shell as root. If you need to run several commands as root, prefix each of them with sudo. a typo.) It is often configured to not ask again for a few minutes so you can run several sudo commands in succession. (The purpose is to limit the damage if you leave your keyboard unattended and unlocked, and also to ensure that you really wish to run that command and it wasn't e.g. Sudo requires that you type your own password. If you don't know a separate root password, use this method. This is the preferred method on most systems, including Ubuntu, Linux Mint, (arguably) Debian, and others. Running a shell command as root sudo (preferred when not running a graphical display)

Put sudo in front of the command, and enter your password when prompted.Use su and enter the root password when prompted.The main two commandline possibilities are:
