batch-file - 为什么我会收到此错误？ - "The syntax of the command is incorrect."

Question

我在下面写了批处理脚本。我无法弄清楚为什么会抛出命令的语法不正确。

我在函数结束时遇到错误 len当 cmd 正在处理 goto :EOF .

:len <inputArrayName> <outputLength>
SETLOCAL
    set arrayName=%1

    )
( ENDLOCAL
    SET "%~2=%arrayIndex%"
)
goto :EOF

你能帮我弄清楚，这里出了什么问题。

D:\Work\shell-scripts\shell-scripts>goto :EOF
The syntax of the command is incorrect.

Answer 1

问题源于您注释掉 call :runzip 的方式.
::从技术上讲，它是一个标签，批处理不允许您在代码块内使用标签(if 语句、for 循环以及括号内的任何其他内容)。要解决此问题，请使用 REM在这些情况下注释掉行。

REM call :runZip "!sourceDir!" "!backupZipFile!" 1>>"%LOG_FILE%"
