Bash Scripting - File Operations in Scripts

The following script is intended to write two lines to output.txt but only writes one line. What is the error?

echo "First line" > output.txt
printf "Second line" > output.txt

Aprintf needs \n to add newline

BSecond command overwrites the file instead of appending

Cecho should use >> to append

DMissing quotes around Second line

Step-by-Step Solution

Solution:

Step 1: Check file redirection operators
The first command uses > which creates or overwrites output.txt with "First line".
Step 2: Check second command redirection
The second command also uses > which overwrites output.txt, replacing previous content.
Step 3: Correct approach
To keep both lines, second command should use >> to append instead of overwrite.
Final Answer:
Second command overwrites the file instead of appending -> Option B
Quick Check:
Using > twice overwrites file = D [OK]

Quick Trick: Use >> to append, > overwrites file [OK]
