Linux CLI - Linux Basics and Terminal

You want to write a Bash script that lists all files in the current directory that have the extension .txt and saves the list to a file named textfiles.txt. Which command should you use inside the script?

Als *.txt > textfiles.txt

Bls *.txt >> textfiles.txt

Ccat *.txt > textfiles.txt

Decho *.txt > textfiles.txt

Step-by-Step Solution

Solution:

Step 1: Understand the goal
You want to list filenames ending with .txt, not their contents, and save that list to a file.
Step 2: Choose correct command
ls *.txt > textfiles.txt lists matching files and overwrites the output file. >> appends, which is not needed here. cat outputs file contents, not names. echo *.txt expands filenames but may not handle many files well.
Final Answer:
ls *.txt > textfiles.txt -> Option A
Quick Check:
List files with ls and redirect output [OK]

Quick Trick: Use ls with > to save file list, not contents [OK]

Common Mistakes:

Using cat instead of ls
Appending instead of overwriting
Using echo which may misbehave
