Master Linux Like a Pro: Dive into the 2026 RHEL Red Hat Challenge!

Changing a user's default shell in Red Hat Enterprise Linux (RHEL) is commonly performed using the `usermod` command with the `-s` option, which allows you to specify the new shell for a user. This command modifies the user account attributes in the system's user database.

By utilizing the syntax `usermod -s [shell_path] [username]`, you instruct the system to set the specified shell (for example, `/bin/bash` or `/bin/zsh`) as the user's default shell. This change will take effect the next time the user logs in, ensuring they interact with the new shell environment.

Understanding the format of the command is also crucial; `usermod` is designed for modifying user accounts, while the `-s` flag specifically indicates that you are changing the shell.

Other options do not reflect the correct command or syntax used within RHEL for changing a user's default shell. For instance, `chsh` is a command available on some distributions but is not the standard command used in RHEL. The command `set-shell` and `moduser` do not exist within standard RHEL command-line tools for user management. The correct understanding of the command structure and the specific flags available within
