The break command allows you to jump out of all loops (terminate the execution of all subsequent loops)

#! / bin/bash

While:

Do

Echo-n "enter a number between 1 and 5:"

Read aNum

Case $aNum in

1 | 2 | 3 | 4 | 5) echo "the number you entered is $aNum!"

*) echo "the number you entered is not between 1 and 5! game over"

Break

Esac

Done

Break instance 2

#! / bin/bash

I, 1

For day in mon tue wed thu fri

Do

Echo "Weeking $((iTunes +)): $day"

If [$I-eq 3]; then

Break

Fi

Done

Execution result

[root@zabbix shell] # sh break.sh

Weeking 1: mon

Weeking 2: tue

The continue command is similar to the break command, except that it does not jump out of all loops, just out of the current loop.

Modify the above example:

#! / bin/bash

While:

Do

Echo-n "enter a number between 1 and 5:"

Read aNum

Case $aNum in

1 | 2 | 3 | 4 | 5) echo "the number you entered is $aNum!"

*) echo "the number you entered is not between 1 and 5!"

Continue

Echo "Game over"

Esac

Done
