Linux CLI - Process Management

You want to create a script that runs top for 10 seconds, saves the output to a file, and then exits. Which command achieves this?

Atop --time=10 > top_output.txt

Btop -d 10 > top_output.txt

Chtop -t 10 > top_output.txt

Dtop -b -n 10 > top_output.txt

Step-by-Step Solution

Solution:

Step 1: Understand top options for batch mode and iterations
top -b runs in batch mode (non-interactive), -n 10 runs 10 iterations, then exits.
Step 2: Check other options
-d sets delay between updates, not total time; htop does not support -t; --time is invalid option.
Final Answer:
top -b -n 10 > top_output.txt -> Option D
Quick Check:
Batch mode + iterations = top -b -n [OK]

Quick Trick: Use top -b -n for batch output to file [OK]
