假设我想跑步

>foo bar

但是bar随我在文件系统中的位置而变化.我想做的就是不必记住bar的正确值，就是将文件fizz保留在各自的文件夹中，以便我可以执行类似call

but bar changes depdending on where I am in my filesystem. What I'd like to do, so I don't have to remember the proper value of bar, is to keep a file fizz in the respective folders so I can do something like call

>foo fizz

这当然是开箱即用的.

which of course doesn't work out of the box. Neither does

>foo < fizz

因为foo不希望输入，只是一个参数.我找到了 Linux解决方案，但没有找到Windows.

because foo doesn't expect input, just a parameter. I found a solution for Linux, but nothing for Windows.

推荐答案

假设fizz包含单行且无空格，即单线

Assuming fizz contains a single line with no whitespace, the one-liner

for /F %i in (fizz) do @foo %i

将做您想要的.如果您要放入fizz的参数可能包含空格，请使用

will do what you want. If the argument you're putting into fizz may contain whitespace, use

for /F "delims=" %i in (fizz) do @foo "%i"

一次传递参数.如果将%字符放入批处理文件中，则将其加倍.

to pass the argument in one piece. Double the % characters if putting this into a batch file.
