What happens if a recursive Bash function does not have a base case?

AThe function will run only once and then stop

BThe function will convert into a loop automatically

CThe function will return an error immediately

DThe function will call itself indefinitely, causing a stack overflow

Step-by-Step Solution

Solution:

Step 1: Understand the role of a base case in recursion
A base case stops the recursion by providing a condition to end the repeated calls.
Step 2: Analyze what happens without a base case
Without a base case, the function keeps calling itself endlessly, using more memory each time until the system runs out of stack space.
Final Answer:
The function will call itself indefinitely, causing a stack overflow -> Option D
Quick Check:
Base case missing = infinite recursion [OK]

Quick Trick: Always include a base case to stop recursion [OK]
