Linux CLI - Viewing and Editing Files

Which of the following is the correct syntax to continuously monitor the file /var/log/auth.log using tail?

Atail -n /var/log/auth.log

Btail /var/log/auth.log -f

Ctail -follow /var/log/auth.log

Dtail -f /var/log/auth.log

Step-by-Step Solution

Solution:

Step 1: Identify correct option placement
The option -f must come immediately after tail before the filename.
Step 2: Verify option correctness
-f is the correct option to follow the file live; -follow is invalid and -n requires a number.
Final Answer:
tail -f /var/log/auth.log -> Option D
Quick Check:
Correct syntax = tail -f /var/log/auth.log [OK]

Quick Trick: Options come before filename; -f not -follow [OK]
