外壳脚本如果-否则情况

Question

我编写了以下脚本来交互式输入服务器名称和服务名称。当 y 在 while 循环结束时作为输入给出时，这会重复询问输入。

key='y';
service='';
serverName='';
while [[ $key == 'y' ]]; do
    echo -e "nEnter serverName  : "
    read serverName
    echo -e "nEnter Service Name  : "
    read service
    if [[ ! -z "$service" ] && [ ! -z "$serverName" ]]; then
        echo -e "startService $serverName $service"
        #echo -e " Atleast one input is null"
    else
        echo -e " Atleast one input is null"
    fi
    echo -e "Enter y to repeat this step. Enter n to exit :"
    read key
done

Answer 1

您的while循环条件是错误的，请像下面这样更正：-

while [[ '$key' == 'y' ]];

或

while [[ $key == y ]];
