Linux CLI - Viewing and Editing Files

Given two files with these contents:

file1.txt:
apple
banana
cherry

file2.txt:
apple
banana
date

What will be the output of diff file1.txt file2.txt?

A2c2 < banana --- > banana

BNo output (files are identical)

C3c3 < cherry --- > date

DError: files not found

Step-by-Step Solution

Solution:

Step 1: Compare lines one by one
Lines 1 and 2 are the same (apple, banana). Line 3 differs: 'cherry' vs 'date'.
Step 2: Understand diff output format
diff shows line number and change type: '3c3' means line 3 changed. Then shows old line with '<' and new line with '>'.
Final Answer:
3c3 < cherry --- > date -> Option C
Quick Check:
Line 3 differs [OK]

Quick Trick: Look for first differing line number in diff output [OK]

MISTAKES
