Which command is used to modify user accounts?

• A. passwd
• B. adduser
• C. usermod
• D. groupmod

Answer: (C)

The command used to modify user accounts is `usermod`. This command allows system administrators to make various changes to existing user accounts. With `usermod`, you can perform tasks such as changing a user's home directory, updating their login shell, adding or removing them from groups, or modifying their account expiration date. The ability to make this range of modifications distinguishes `usermod` as the go-to tool for altering the settings of user accounts on a Linux system. In contrast, the other commands have more specific functions. The `passwd` command is primarily used to change a user's password, while `adduser` is intended for creating new user accounts. The `groupmod` command is designed for modifying existing groups, not users. Understanding the specific capabilities of these commands helps in effectively managing user accounts within a Linux environment.
