Question

我遇到以下检查布尔变量的麻烦：

for i in "${list[@]}"
do
        if [ $i = "web.war" ] ; then
        $deployed = true; echo "Deployed!!!!!";
        fi
done

echo $deployed;

在这个例子中，条件$ i =＆＃34; web.war＆＃34;实际上是文本＆＃34; 已部署＆＃34;打印出来。但是，当我在最后一行打印时，变量$ deployed的值为false。是变量范围的问题还是什么？感谢

Answer 1

$deployed = true

对于作业，请删除$和空格。

deployed=true

Shellcheck.net是一个很棒的网站，用于检查shell脚本的语法错误，常见错误，拼写错误等。例如，这是为您的代码段打印的内容。

Line 1:
for i in "${list[@]}"
          ^-- SC2154: list is referenced but not assigned.

Line 3:
        if [ $i = "web.war" ] ; then
             ^-- SC2086: Double quote to prevent globbing and word splitting.

Line 4:
        $deployed = true; echo "Deployed!!!!!";
         ^-- SC1066: Don't use $ on the left side of assignments.
                  ^-- SC1068: Don't put spaces around the = in assignments.
