![]() The sudo command will still need to be used for root access though. These instructions are to remove the prompt for a password when using the sudo command. You might want to read the sudoers and vi manual pages for additional information. Hit Ctrl+ X, then Y, then Enter to save your file and exit nano. If you made a mistake, perhaps the easiest way is to redo from start, to exit without saving (hit Escape to enter the command mode) and then type :q! Enter. Now, if you're happy with your editing, type in :w Enter to write the file and :q Enter to exit vi. (vi!) hit Escape to return to command mode. If you specify a negative value, the timeout will never expire. If you specify 0 you will always be asked the password. Where X is the timeout expiration in minutes. (vi!) press the A (capital "a") key to move at the end of the current line and enter editing mode (append after the last character on the line). Use the arrow keys to move to the end of the Defaults line. (Vi specific instructions noted with (vi!). ![]() You're now a super user editing one of the most important files on your system. This opens an editor and points it to the sudoers file - Ubuntu defaults to nano, other systems use Vi. I'll lay out all examples but be warned it is very risky any way you do this although this way is much safer: sudo visudo Root sudo timeouts are the easiest and safest way of doing this. See /etc/sudoers.d/README and man sudoers for more information. Similarly, one file can be used to manage multiple directives: echo "username ALL=(ALL:ALL) NOPASSWD: ALL" | sudo tee -a /etc/sudoers.d/local echo "otheruser ALL=(ALL:ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/otheruser If you want to do that for a different user, just replace both instances of $USER with some other username in the above command. This will create a file called /etc/sudoers.d/$USER (where $USER is the username of the user that you were logged in as when you ran that command), making it clear which users are granted permission. To make the currently logged in user a a sudoer and make sudo not prompt them for a password, use echo "$USER ALL=(ALL:ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/$USER This separates local changes from the default policy and saves time in case the distribution sudoers file changes. The preferred way to grant individual (or group) permissions would be to add files under /etc/sudoers.d You'll still be prompted for your password if you (for example) try to install a package from the software center This only applies, to using the sudo command in the terminal. YOUR_USERNAME_HERE ALL=(ALL) NOPASSWD: ALLĪfter this you can type sudo in a Terminal window without being prompted for the password. # See sudoers(5) for more information on "#include" directives: # Allow members of group sudo to execute any command # Members of the admin group may gain root privileges # See the man page for details on how to write a sudoers file.ĭefaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin" # Please consider adding local content in /etc/sudoers.d/ instead of # This file MUST be edited with the 'visudo' command as root. Save and close the sudoers file (if you haven't changed your default terminal editor (you'll know if you have), press Ctl + x to exit nano and it'll prompt you to save).Īs of Ubuntu 19.04, the file should now look something like # Where $USER is your username on your system. In the bottom of the file, add the following line: $USER ALL=(ALL) NOPASSWD: ALL Open a Terminal window and type: sudo visudo If you have already edited your /etc/sudoers file, either return it to its original unedited state and use the 10-installer file for configuration, or delete the /etc/sudoers.d/10-installer file and use the direct edits to the /etc/sudoers instead.You can configure sudo to never ask for your password. If you want to enable passwordless sudo privileges for the wheel group, change that line to: ![]() The 10-installer file gives sudo privileges to all members in the wheel group. pacnew file (.pacnew files must be handled - carefully - by the user).ĭrop-in files for sudoers can also make management of multiple users easier if there are a number of users on the system. This has the advantage of the system being able to update the original file (to add new features, new syntax, etc) without creating a. Notice the last line of /etc/sudoers: # Read drop-in files from /etc/sudoers.dĭrop-in files allow modifications to the default configuration of a file without physically editing the file itself. The /etc/sudoers.d/10-installer file is a drop-in file used for configuration. Well, it’s granting sudo privileges to all members of the wheel group, which is at least a little special. It seems to not be doing anything special ![]()
