Bash Scripting - Loops

Which of the following is a correct way to start an infinite loop in bash?

A<code>if true; then echo Loop; fi</code>

B<code>for i in 1..10; do echo $i; done</code>

C<code>while false; do echo No; done</code>

D<code>while true; do echo Hello; done</code>

Step-by-Step Solution

Solution:

Step 1: Understand infinite loop syntax
In bash, while true runs the loop forever because the condition is always true.
Step 2: Check each option
while true; do echo Hello; done uses while true correctly. for i in 1..10; do echo $i; done loops 10 times, not infinite. if true; then echo Loop; fi is a conditional, not a loop. while false; do echo No; done never runs because condition is false.
Final Answer:
<code>while true; do echo Hello; done</code> -> Option D
Quick Check:
Infinite loop = while true [OK]

Quick Trick: Infinite loops use always-true conditions like 'while true' [OK]
