Linux Foundation Certified System Administrator (LFCS) — Question 110

Which of the following commands set the sticky bit for the directory /tmp? (Choose TWO correct answers.)

Answer options

• A. chmod +s /tmp
• B. chmod +t /tmp
• C. chmod 1775 /tmp
• D. chmod 4775 /tmp
• E. chmod 2775 /tmp

Correct answer: B, C

Explanation

The sticky bit is set using the command 'chmod +t', which is option B. Additionally, option C, 'chmod 1775 /tmp', includes the sticky bit in its numeric representation (1 at the beginning), making it a valid choice as well. The other options do not set the sticky bit correctly.
