If you want to run some binary executable (e.g. This will run the commands inside the script file without asking for a password.Īnother possibility might be to install, configure, then use the super command to run your script as super /path/to/your/script Now when running the command add sudo before it like: sudo. Replace ahmad with whatever your username is. Open the sudoers file: sudo visudo -f /etc/sudoersĪdd the following line at the end: ahmad ALL=(root) NOPASSWD: /home/ahmad/create_dir.sh
Make changes so that this script doesn’t require a password. Save and exit (using :wq!)Īssign execute permissions to it using: sudo chmod u+x create_dir.sh The script will be created in the user’s home directoryĪdd some commands that only a root or sudo user can execute like creating a folder at the root directory level: mkdir /abc See comments belowĬomplete Solution: The following steps will help you achieve the desired output:Ĭreate a new script file (replace create_dir.sh with your desired script name): vim ~/create_dir.sh WARNING: This answer has been deemed insecure. Make sure that you have Defaults env_reset in /etc/sudoers or that this option is the compile-time default ( sudo sudo -V | grep env should include Reset the environment to a default set of variables). Note for readers who aren't running Ubuntu or who have changed the default sudo configuration (Ubuntu's sudo is ok by default): Running shell scripts with elevated privileges is risky, you need to start from a clean environment (once the shell has started, it's too late (see Allow setuid on shell scripts), so you need sudo to take care of that). (Don't give more permissions than the minimum required unless you've thought out the implications.) Note the use of (root), to allow the program to be run as root but not as other users.
Myusername ALL = (root) NOPASSWD: /path/to/my/program
#Run grandperspective as root password
Therefore, if you can execute any command with a password prompt, and you want to be able to execute a particular command without a password prompt, you need the exception last. If there are multiple matching entries in /etc/sudoers, sudo uses the last one.
