Apply write permission for new ubuntu user

To apply write permission for a new Ubuntu user, you can follow these steps:

Method 1: Using the usermod command

  1. Open a terminal as the root user (or use sudo to elevate your privileges).
  2. Use the usermod command to modify the permissions for the new user:
    sudo usermod -aG wheel <new_username>

    Replace <new_username> with the actual username of the new user.

This will add the new user to the wheel group, which has write permissions by default.

Method 2: Using the adduser command

  1. Open a terminal as the root user (or use sudo to elevate your privileges).
  2. Use the adduser command to create a new user and add them to the wheel group:
    sudo adduser <new_username> wheel

    Replace <new_username> with the actual username of the new user.

Method 3: Using the visudo command

  1. Open a terminal as the root user (or use sudo to elevate your privileges).

  2. Use the visudo command to edit the /etc/sudoers file:

    sudo visudo

  3. Add the following line at the end of the file:

    <new_username> ALL=(ALL) NOPASSWD:ALL

    Replace <new_username> with the actual username of the new user.

  4. Save and exit the editor.

This will give the new user full permissions to execute any command without a password.

Additional steps

To ensure that the new user has write permissions to specific directories or files, you can use the chmod command to change the permissions. For example:

sudo chown -R <new_username>:<new_username> /path/to/directory

This will change the ownership of the specified directory and all its contents to the new user.

Alternatively, you can use the chmod command to set specific permissions for the new user:

sudo chmod -R u+w /path/to/directory

This will set the write permission for the new user on the specified directory and all its contents.

Remember to replace <new_username> with the actual username of the new user, and /path/to/directory with the actual path to the directory or file you want to modify.
