You want to recursively compare two directories projectA and projectB, ignoring all differences in whitespace. Which diff command should you use?

Adiff -r -w projectA projectB

Bdiff -r -i projectA projectB

Cdiff -w projectA projectB

Ddiff -q projectA projectB

Step-by-Step Solution

Solution:

Step 1: Understand options
-r enables recursive directory comparison; -w ignores all whitespace differences.
Step 2: Evaluate options
diff -r -i projectA projectB ignores case (-i), not whitespace. diff -w projectA projectB lacks recursion. diff -q projectA projectB only reports if files differ, no details.
Final Answer:
diff -r -w projectA projectB -> Option A
Quick Check:
Use -r for recursion and -w to ignore whitespace [OK]

Quick Trick: Use -r for recursion and -w to ignore whitespace [OK]
