CompTIA Linux+ (XK0-004) — Question 86

Joe, a user, is unable to log in to the server and contracts the systems administrator to look into the issue. The administrator examines the /etc/passwd file and discovers the following entry: joe:x:505:505::/home/joe:/bin/false
Which of the following commands should the administrator execute to resolve the problem?

Answer options

• A. usermod ג€"s /bin/bash joe
• B. passwd ג€"u joe
• C. useradd ג€"s /bin/bash joe
• D. chage ג€"E -l joe

Correct answer: A

Explanation

The correct command is A, as it changes Joe's shell from /bin/false to /bin/bash, allowing him to log in. Option B only unlocks a user account that may be locked, which isn't the issue here. Option C would create a new user instead of modifying the existing one, and option D doesn't address the shell issue at all.
