What will be the output of the following command if file.txt exists?
cat file.txt && echo 'File found' || echo 'File missing'

A'File found' only

B'File missing' only

CContents of file.txt followed by 'File found'

DContents of file.txt followed by 'File missing'

Step-by-Step Solution

Solution:

Step 1: Analyze cat command success
If file.txt exists, cat file.txt succeeds and prints its contents.
Step 2: Understand chaining behavior
Because cat succeeds, && runs echo 'File found'. The || part is skipped since the left side succeeded.
Final Answer:
Contents of file.txt followed by 'File found'. -> Option C
Quick Check:
Success && echo runs, failure || echo skipped [OK]

Quick Trick: && runs next on success; || runs next on failure [OK]
