How do I grant sudo access?

To grant sudo access to a user in a Linux system, you can follow these steps:

Add the user to the sudo group (replace username with the actual username):
```
sudo usermod -aG sudo username
```
Verify that the user has been added to the sudo group:
```
groups username
```
The output should include the "sudo" group.
Test the sudo access by switching to the user and running a command that requires sudo privileges:
```
sudo su - username
sudo command_to_run
```
Exit the user session to return to your original user:
```
exit
```

This process allows the specified user to execute commands with elevated privileges using sudo.
