Linux create new user

To create a new user in Linux, you can use the useradd command. Here are the basic syntax and options:

Basic Syntax:

useradd [options] username

Options:

• -m or --create-home: Create a home directory for the new user.
• -s or --shell: Specify the default shell for the new user.
• -g or --group: Specify the primary group for the new user.
• -G or --groups: Specify additional groups for the new user.
• -p or --password: Set the password for the new user.

Example:

useradd -m -s /bin/bash -g users newuser

This command creates a new user named newuser with a home directory, sets the default shell to /bin/bash, and assigns the user to the users group.

Alternative Method: You can also use the adduser command, which is a more user-friendly alternative to useradd. Here's an example:

adduser newuser

This command will prompt you to enter the password for the new user, and then create the user with default settings.

Additional Options:

• -d or --home-dir: Specify a custom home directory for the new user.
• -c or --comment: Specify a custom comment for the new user.
• -e or --expire-date: Specify an expiration date for the new user's account.

Example with additional options:

useradd -m -s /bin/bash -g users -d /home/newuser -c "New User" -e 2023-12-31 newuser

This command creates a new user named newuser with a home directory, sets the default shell to /bin/bash, assigns the user to the users group, specifies a custom home directory, sets a custom comment, and sets an expiration date for the account.

Remember to replace newuser with the desired username, and adjust the options as needed for your specific use case.
