Today, I learned how to give the permissions to the new user.
Like if we want to give root permission to the newly created user then type
It will open a file
Add a new line in it
username ALL=(ALL) ALL
and then save the settings.
To switch to other user account type
and then type root password.
And I today worked upon OSM also and will publish my post soon.
We all today enjoyed party also. My best friend Deepti sung a song also. Really enjoye also.
