Linux CLI - Pipes and Redirection

You want to append output to log.txt instead of overwriting it. Which command fixes the error in this script?

ls -l | tee log.txt

Als -l > tee -a log.txt

Bls -l | tee > log.txt

Ctee -a ls -l log.txt

Dls -l | tee -a log.txt

Step-by-Step Solution

Solution:

Step 1: Identify the need to append output
The default tee overwrites files. To append, use the -a option.
Step 2: Check correct syntax for appending
ls -l | tee -a log.txt correctly uses tee -a log.txt with pipe from ls -l. Others misuse redirection or order.
Final Answer:
ls -l | tee -a log.txt -> Option D
Quick Check:
Use -a with tee to append = C [OK]

Quick Trick: Add -a option to tee to append instead of overwrite [OK]
