Using Command Prompt To Call a Batch File in a Sub-Directory
提问by KevinO
I'd like to use a batch file to call a different batch file that is in a sub directory. For instance, if my file system look as follows:
我想使用批处理文件来调用子目录中的不同批处理文件。例如，如果我的文件系统如下所示：
MainFolder
main.bat
FirstDirectory
SecondDirectory
foo.bat
MainFolder
main.bat
FirstDirectory
SecondDirectory
foo.bat
Then main.bat might look something like this:
然后 main.bat 可能看起来像这样：
echo on
REM This lines tells the user what this bat file is doing
call ant
call \SecondDirectory\foo.bat
I'm looking for a one line solution which I think does not exist. Unfortunately I don't always want to do this with a batch file and want to do it directly from the command line.
我正在寻找一种我认为不存在的单行解决方案。不幸的是，我并不总是想使用批处理文件来执行此操作，而是想直接从命令行执行此操作。

You can indeed call a batch file from another batch file using the callcommand. As @Blorgbeard states, the issues is the leading backslash \. Removing it indicates SecondDirectoryis relative to the current working directory.
您确实可以使用该call命令从另一个批处理文件调用批处理文件。正如@Blorgbeard 所说，问题是主要的反斜杠\。删除它表示SecondDirectory相对于当前工作目录。
call SecondDirectory\foo.bat
A word of caution: the callcommand essentially inserts called code in at run time. Be careful to avoid variable name collisions.
提醒一句：该call命令本质上是在运行时插入被调用的代码。小心避免变量名冲突。
