LPIC-1 Administrative Tasks Practice Question
An administrator needs to display the current and previous runlevels of a Linux system. Which command provides this information?
⚠ Common exam trap
Candidates often confuse `who -r` with `runlevel` because both display the current runlevel, but `who -r` omits the previous runlevel, which is the key piece of information the question explicitly asks for.

Correct answer & explanation
✓
runlevel
The `runlevel` command displays both the previous and current runlevels of a Linux system. It outputs two characters: the first indicates the previous runlevel (or 'N' if the runlevel has not changed since boot), and the second indicates the current runlevel. This is the standard tool for querying runlevel information on SysV init systems.
