Bash Scripting - File Operations in Scripts

What will be the output in report.txt after running this script?

printf "Line1\n" > report.txt
printf "Line2" >> report.txt
echo "Line3" >> report.txt

ALine1\nLine2\nLine3\n

BLine1\nLine2\nLine3

CLine1Line2Line3

DLine1\nLine2Line3\n

Step-by-Step Solution

Solution:

Step 1: Check each command's output
First printf writes 'Line1' plus newline. Second printf writes 'Line2' without newline. echo writes 'Line3' plus newline.
Step 2: Combine outputs carefully
File content: Line1\nLine2Line3\n because Line2 and Line3 are on same line.
Final Answer:
Line1\nLine2Line3\n -> Option D
Quick Check:
printf without \n does not add newline [OK]

Quick Trick: printf needs explicit \n for newline [OK]
