The logger command is a Linux utility that

• A. Writes data to the system log
• B. Prints server banners on login
• C. Resets the system timer
• D. Updates package lists

Answer: (A)

This question tests what the logger command does: it writes messages to the system log via the syslog service. When you run logger with a message, that text is forwarded to syslog, which then records it in the appropriate log files (such as /var/log/syslog or /var/log/messages) or the systemd journal, depending on your system setup. You can refine what gets logged with options to set the priority and tag, making it a handy tool for scripting and diagnostics. The other tasks described—displaying a banner on login, resetting a timer, or updating package lists—are handled by different components (motd/login mechanisms, time/timer utilities, and the package manager, respectively).
