Sudo Command in Linux With Examples

The sudo command in Linux allows users to run commands with superuser (root) privileges, enhancing security by limiting root access.

Examples:

1. Run a command as root:
   bash

   CopyEdit

   sudo apt update

2. Edit a system file:
   bash

   CopyEdit

   sudo nano /etc/hosts

3. Switch to root shell:
   bash

   CopyEdit

   sudo -i

4. Execute as another user:
   bash

   CopyEdit

   sudo -u username command

5. View sudo privileges:
   bash

   CopyEdit

   sudo -l


Use sudo cautiously, as improper use can affect the system. Non-root users must be added to the /etc/sudoers file or the sudo group.
