Linux screening

Enter the code your interviewer gave you.

Before you start

Hello . Please read this — it takes 30 seconds.

• questions, one at a time.
• per question — harder questions get more. The countdown is always on screen. When it reaches zero the question is submitted as it stands and the next one opens.
• You cannot go back. There is no review screen at the end.
• You will not be told whether an answer was right. That is deliberate, and it is not a reflection of how you are doing.
• Short-answer questions accept any reasonable form of the command. Don't worry about exact spacing.

This quiz is one small input among several, and it is not what the hiring decision rests on. Answer from what you know — the time per question is short on purpose, so looking things up will cost you more time than it saves.

That's everything
