Why doesn't for loop work in bash?

Question

bash

Good afternoon! I need to write a script to check the length of an array in a loop, but something doesn't work (the actual script itself:

#!/bin/bash
#останавливаем службу
systemctl stop libvirt-guests
#объявляю массив и складываю в него результаты команды
unset array
array=(`virsh list | grep running | awk '{print $2}'`)
lenArr=${#array[@]}
#вот тут необходимо в бесконечном цикле проверять пока длина массива не будет равна 0
#и только тогда выполнить echo.
state=false
while [ state = true ]
        do
        if  [ "$lenArr" -eq 0 ] ; then
                echo "shutdown success"
                state=true
                break
        else
                continue
        fi
done

Answer 1

state=false
while [ state != true ]
        do
        if  [ "$lenArr" -eq 0 ] ; then
                echo "shutdown success"
                state=true
                break
        else
                continue
        fi
done

You set state equal to false, and then compare it with true, you have to check for equality, but you need to check for NOT equality by logic :)
