Within the free software operating systems Linux is one of the most reliable, in which there are commands that are needed to optimize the work, in addition to achieving better performance. Which you can achieve by optimizing and cleaning the Ubuntu system.
Of course, these softwares also bring systems that serve as distribution, in this case it is called Ubuntu, it was designed for desktop computers, as well as educational servers.
As there are different types of command, sometimes it is necessary to configure, modify and use with time limits. Here we are going to see make these changes to the Sudu command within the Ubuntu operating system and if yours is a bit outdated you should think about updating the Ubuntu system to the latest version.
Before we are going to know what Sudu and Ubuntu are and what they are for , also how to modify and configure the sudu grace period in Ubuntu?
Learn how to configure sudo grace period in Ubuntu to enhance your workflow. Avoid repetitive password entry by following this step-by-step guide.
Configuring the sudo grace period in Ubuntu involves editing the sudoers file. This file controls the sudo configuration, including the timeout period. By default, the timeout is set to 15 minutes, but you can customize it to your preference. Here’s a tabular guide to help you through the process:
| Step | Action | Description |
|---|---|---|
| 1 | Open Terminal | Open a terminal window in Ubuntu. |
| 2 | Edit sudoers File | Type sudo visudo in the terminal. This opens the sudoers file in a safe way, preventing syntax errors. |
| 3 | Locate Defaults Line | Look for a line that starts with Defaults. If it’s not there, you can add it. |
| 4 | Set Timeout Value | Add or modify the line to include Defaults timestamp_timeout=X, where X is the number of minutes you want for the grace period. If you set X to 0, it will always ask for a password. If you set it to a negative value, the timeout is disabled, and sudo will never ask for a password again after the first time. |
| 5 | Save and Exit | Save the file and exit. In visudo, this is typically done by pressing Ctrl+X, then Y (for Yes), and Enter. |
| 6 | Test Configuration | Test your new settings by using a sudo command, waiting longer than your set period, and then using another sudo command to see if it asks for a password again. |
Important Notes:
- Be cautious while editing the
sudoersfile. An incorrect configuration can lock you out of sudo privileges. - Always use
visudoto edit thesudoersfile as it checks for syntax errors. - The changes will take effect immediately after saving the file.
- The
timestamp_timeoutis set in minutes. If you need a specific time in seconds, you would need to convert it to minutes (e.g., 30 seconds would be 0.5 minutes).
What is Sudu and what is it for?

You just have to remember that you have to have experience so as not to cause difficulties, since you will have everything under your responsibility.
What you should know is that these privileges have times or periods of duration so we are going to learn how to change and configure this Sudu command in Ubuntu Linux.

Step 4
At the end of that text put the time chosen by you, now we save the changes that of the grace period. This means that the operating system will keep my user password for the time that you put in the text that we mentioned before.
