Which of the following commands shows all active systemd timers?

Question

Options

• Asystemctl-timer show
• Btimectl list
• Csystemctl -t
• Dsystemctl list-timers
• Etimeq

• A
  4% (1)
• B
  8% (2)
• D
  76% (19)
• E
  12% (3)

Explanation

systemctl list-timers is the correct command because systemctl is the primary interface for interacting with systemd, and list-timers is a valid subcommand that displays all active timers along with their next trigger time, last trigger time, and associated service unit.

The distractors fail for these reasons:

• A (systemctl-timer show) - systemctl-timer is not a real command; the correct binary is systemctl (no hyphen before "timer")
• B (timectl list) - timectl is a fabricated command; the real timedatectl manages system time/timezone settings, not timers
• C (systemctl -t) - -t is a flag that filters by unit type (e.g., systemctl -t service), not a standalone command for listing timers
• E (timeq) - this command does not exist in standard Linux distributions

Memory tip: Think of it as "list what's ticking" - systemctl list-timers follows the same pattern as systemctl list-units and systemctl list-sockets, so if you can list units, you can list timers the same way.
