Question

所以我有一个包含大if / fi块的shell脚本，它工作正常，直到我决定为这个大else放置if个案例} / fi阻止。现在我收到了这个错误：

/root/VVPN/Scripts/scriptPrincipal.sh: line 201: syntax error near unexpected token `else'
/root/VVPN/Scripts/scriptPrincipal.sh: line 201: `else'

我经历了8到10次stackoverflow帖子，其中人们有完全相同的错误，除了所有这些都是简单的语法错误，如if语句的[之后缺少空格，或{{1} }而不是:关键字之前的;，或then用于已else关闭的if等等...（你明白了fi）。

但是，我一遍又一遍地检查了我的代码中的所有这些错误，并且在:p / if / else语法方面，一切似乎都是正确的。我甚至向一些同事展示了代码，他们也找不到这个错误的原因。

以下是代码：

fi

所以错误中提到的else（在第201行）实际上是代码中的最后一个。没有这个以及后面的回声，脚本工作正常。

如果[$ CP = $ N]如下所示，您是否可以更改;

if [ "$CP" == "$N" ]

这不是别的问题;例如;如果运行以下代码，则输出相同。所以你应该将其他命令集中在if语句中。

CP="continue1"
if [ ${CP} != "continue" ]
then
   while   #this is wrong 
   echo ok
   echo ok
   echo ok
else
fi

./test.sh: line 8: syntax error near unexpected token `else'
./test.sh: line 8: `else'

Shell if if else语法错误，而实际语法似乎正确
