The current Linux manual pages for su define it as "substitute user", [9] making the correct meaning of sudo "substitute user, do", because sudo can run a command as other users as well. [10] [11] Unlike the similar command su, users must, by default, supply their own password for authentication, rather than the password of the target user.
The wheel group is a special user group used on some Unix systems, mostly BSD systems, [citation needed] to control access to the su [4] [5] or sudo command, which allows a user to masquerade as another user (usually the super user). [1] [2] [6] Debian and its derivatives create a group called sudo with purpose similar to that of a wheel group. [7]
Despite being a simple design, make menuconfig offers considerable advantages to the question-and-answer-based configuration tool make config, the most notable being a basic search system and the ability to load and save files with filenames different from ".config".
[7] These commands are only effective in the long-run if the user makes the changes persistent. However, the settings the user can set via hdparm are reverted each time the system is rebooted. Therefore, it might be wise to restore the personal settings upon boot. An appropriate place that exists in most Linux distributions is the /etc/rc.local ...
It is also possible to use polkit to execute commands with elevated privileges using the command pkexec followed by the command intended to be executed (with root permission). [9] However, it may be preferable to use sudo , as this command provides more flexibility and security, in addition to being easier to configure.
aptitude is a front end to APT, the Debian package manager. [4] It displays a list of software packages and allows the user to interactively pick packages to install or remove. It has a search system utilizing flexible search patterns. It was initially created for Debian, but has appeared in RPM-based distributions as well.
passwd is a command on Unix, Plan 9, Inferno, and most Unix-like operating systems used to change a user's password.The password entered by the user is run through a key derivation function to create a hashed version of the new password, which is saved.
In Unix and Unix-like operating systems, chmod is the command and system call used to change the access permissions and the special mode flags (the setuid, setgid, and sticky flags) of file system objects (files and directories).
