Detailed explanation-1: -Use the break statement to exit a while loop when a particular condition realizes. The following script uses a break inside a while loop: #!/bin/bash i=0 while [[ $i-lt 11 ]] do if [[ “$i” == ‘2’ ]] then echo “Number $i!” break fi echo $i ((i++)) done echo “Done!"

Detailed explanation-2: -The if statement starts with the if keyword followed by the conditional expression and the then keyword. The statement ends with the fi keyword. If the TEST-COMMAND evaluates to True, the STATEMENTS gets executed. If TEST-COMMAND returns False, nothing happens; the STATEMENTS get ignored.
