Git-bash 字符串变量返回为 null

Question

问题与和 100 多个类似的其他 SO 线程有关。我有一个像下面这样的变量及其用法：

branchtochechout = "develop"

echo "Branch To Chechout is : $branchtochechout" 

for thedir in ./*/ ; 
 do ( 
  echo -e "Checking out in the directory:$thedir"; 
  cd "$thedir" && git checkout $branchtochechout); 
  sleep 2
 done

令我惊讶的是，$branchtochechout 在 echo 语句以及 for 循环中都为我提供了 null。 git-bash (windows) 的工作方式与 linux bash 脚本不同吗？请帮助我了解我在这里做错了什么？

您不能在变量赋值中将空格放在 = 周围。
另外，引用您的变量，并添加一个 shebang。
尝试 https://www.shellcheck.net/

Line 1:
branchtochechout = "develop"
^-- SC2148 (error): Tips depend on target shell and yours is unknown. Add a shebang or a 'shell' directive.
                 ^-- SC2283 (error): Remove spaces around = to assign (or use [ ] to compare, or quote '=' if literal).

Line 3:
echo "Branch To Chechout is : $branchtochechout"
                              ^-- SC2154 (warning): branchtochechout is referenced but not assigned.

Line 8:
  cd "$thedir" && git checkout $branchtochechout);
                               ^-- SC2086 (info): Double quote to prevent globbing and word splitting.

Did you mean: (apply this, apply all SC2086)
  cd "$thedir" && git checkout "$branchtochechout");
