sudo (/ s uː d uː / [4]) is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. [5] It originally stood for "superuser do", [ 6 ] as that was all it did, and this remains its most common usage; [ 7 ] however, the official Sudo project ...
In this mode users can assume the user environment of the target user. john@localhost:~$ su - jane Password: jane@localhost:~$ The command sudo is related, and executes a command as another user but observes a set of constraints about which users can execute which commands as which other users (generally in a configuration file named /etc ...
On Gentoo Linux, installing software Preferences screen: Global tab Preferences screen: Profile tab. GNOME Terminator is a free and open-source terminal emulator for Linux programmed in Python, licensed under GPL-2.0-only. The goal of the project is to produce a useful tool for arranging terminals.
Widely used terminal emulator programs include xterm, GNOME Terminal, Konsole, and Terminal. Remote login servers such as Secure Shell and Telnet servers play the same role but communicate with a remote user instead of a local one. Screen and Tmux are used to add a session context to a pseudoterminal, making for a much more robust and versatile ...
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 script.
In some cases, the actual name of the account is not the determining factor; on Unix-like systems, for example, the user with a user identifier (UID) of zero is the superuser [i.e., uid=0], regardless of the name of that account; [1] and in systems which implement a role-based security model, any user with the role of superuser (or its synonyms ...
will answer the prompts for confirmation with y, effectively installing foobar with sudo apt without any prompts. This usage may be obsolete today, as most commands that would request response from the user have either a 'force' option (e.g., rm-f) or an 'assume-yes' option (for example,apt-y). As an example, the following: $
This example shows tee being used to bypass an inherent limitation in the sudo command. sudo is unable to pipe the standard output to a file. By dumping its stdout stream into /dev/null, we also suppress the mirrored output in the console. The command above gives the current user root access to a server over ssh, by installing the user's public ...
