Question

我正在尝试通过bash脚本在中止上执行“not”，以便当被调用的脚本返回ok时它会中止，反之亦然，它不会中止。

我正在尝试这个

var newWindowRef = $window.open(url, name);
if (newWindowRef) {
    if (newWindowRef.document.body) { // not working on IE
        newWindowRef.document.title = "Downloading ...";
        newWindowRef.document.body.innerHTML = '<h4>Your file is generating ... please wait</h4>';
    }

    var interval = setInterval(function() {
        if (!!newWindowRef.closed) {
            // Downloading completed
            clearInterval(interval);
        }
    }, 1000);
} else {
    $log.error("Opening new window is probably blocked");
}

但我不知道如何将两者结合起来。

Answer 1

if my_process; then
    echo "Program did not fail as expected. Bad!" 
    exit -1
else
    echo "Program failed as expected. Good!" 
fi

Answer 2

作为if / else的替代方案，您可以将&&和||运算符与groups命令一起使用：

my_process && { echo "Program did not fail as expected. Bad!"; exit -1; } \
    || echo "Program failed as expected. Good!"

Answer 3

使用你的速记延伸约翰的回答：

! my_process && echo "Program failed as expected. Good!" || echo "Program did not fail as expected. Bad!" && exit -1

!运算符否定条件布尔值，因此您可以使用&& .. || ..。

编辑请注意，这并不像John更有用的代码那么清晰 - 只是为了表明您可以使用三元风格的语法。更喜欢John's answer的可读性。

当进程不中止时使bash中止，反之亦然
