推荐答案

如果你是支持.Net 2.0的Windows版本， PowerShell 可从命令行获得.Net的全部功能。还有许多内置的小命令。下面的示例将解决您的问题。我使用命令的全名，有更短的别名，但这给了你Google的一些东西。

If you are on Windows version that supports .Net 2.0, I would replace your shell. PowerShell gives you the full power of .Net from the command line. There are many commandlets built in as well. The example below will solve your question. I'm using the full names of the commands, there are shorter aliases, but this gives you something to Google for.

(Get-Content test.txt) | ForEach-Object { $_ -replace "foo", "bar" } | Set-Content test2.txt
