how to run a cmd.exe batch file in a sub shell
提问by Martin
I have a batch file that I usually invoke like this:
我有一个批处理文件，我通常像这样调用它：
longjob.cmd >result.txt 2>&1
This works fine, but the script changes directory during its execution leaving my shell in that directory - which is a nuisance.
这工作正常，但脚本在执行过程中更改了目录，将我的 shell 留在该目录中 - 这很麻烦。
Is there a way to run the command within a sub-shell - while still allowing the output to be captured ?
有没有办法在子 shell 中运行命令 - 同时仍然允许捕获输出？
I have tried
我试过了
cmd longjob.cmd >result.txt 2>&1
which just sits waiting for an exit command.
它只是等待退出命令。
Also I tried
我也试过
start longjob.cmd >result.txt 2>&1
which does run the script, but in a new window and all output is sent to that window instead of the file.
它确实运行脚本，但在一个新窗口中，所有输出都发送到该窗口而不是文件。

Try
尝试
CMD /C longjob.cmd >result.txt 2>&1
Not sure how it'll deal with the redirection, but CMD /C lets you tell CMD what to run and that it should exit when done. (CMD /K lets you tell it to run something but stick around when done.) It will re-use the existing console window if run within one.
不确定它将如何处理重定向，但是 CMD /C 可以让您告诉 CMD 要运行什么以及它应该在完成后退出。（CMD /K 可以让你告诉它运行一些东西，但在完成后坚持下去。）如果在其中运行，它将重新使用现有的控制台窗口。
