How to create a user in ubuntu with password giving all permissions ?

 o create a new user in Ubuntu with a password and grant them all permissions (including administrative privileges), follow these steps:

1. Create a New User

Run the following command, replacing username with your desired username:


sudo adduser username
  • You will be prompted to enter a password and some optional details.

2. Add User to the Sudo Group

To grant full administrative permissions, add the user to the sudo group:


sudo usermod -aG sudo username
  • This allows the user to execute commands as root using sudo.

3. Verify the User’s Permissions

Switch to the new user:


su - username

Then check if the user can run sudo commands:


sudo whoami

If it returns root, the user has full administrative access.

4. (Optional) Grant Passwordless Sudo Access

If you want the user to execute sudo commands without entering a password:


echo "username ALL=(ALL) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/username

Now the user has full administrative privileges.

How to get Ranking of the Students in Excel using RANK Function


=RANK(number,ref,[order])

To rank in descending order, we will use the formula =RANK(B2,($C$5:$C$10),0)

If we want unique ranks, we can use the formula:

=RANK(C5,$C$5:C$10,0)+COUNTIF($C$5:C5,C5)-1

For ascending order, the formula would be:

=RANK.EQ(C5,$C$5:C$10,1)+COUNTIF($C$5:C5,C5)-1

Friday, December 13, 2024

Prevent duplicate entry in excel.

On the Settings tab, choose "Custom" from the Allow drop down list and enter =COUNTIF($D:$D,D2)=1 into the Formula box
