What Is Sudo Su - Postgres

Do you ever worry about who has access to your sensitive information on your Linux system? Well, fear no more! With the easy-to-use sudo command, you can control who has access to what on your system.

The sudo command allows you to give specific users or groups access to certain commands or files without giving them full administrative privileges. This is particularly useful when you have multiple users on a system and want to limit their access to important files or programs.

To use sudo, simply add the command "sudo" before the command you want to execute. For example, if you want to install a new program, instead of just typing "install" in the command line, type "sudo install" to give yourself temporary root privileges to execute the command.

But how do you control who has access to sudo? By default, any user with administrative privileges has access to sudo. However, you can customize this by editing the sudoers file. This file allows you to specify which users or groups can use sudo and which commands they have access to.

Editing the sudoers file can be a bit intimidating at first, but it's actually quite simple. Simply use the "visudo" command to open the file in the default text editor, and then add in your custom configurations. Make sure to save and exit the file when you're done.

One important thing to keep in mind is that any mistakes in the sudoers file can completely lock you out of your system, so make sure to double-check your configurations before saving. You can use the "sudo visudo -c" command to check for syntax errors before saving.

Overall, using sudo is a great way to control who has access to important files and commands on your Linux system. With a little bit of customization, you can ensure that your system stays secure and protected from unwanted users.
