This is a Powershell question similar to what was being asked in this C# question: C# Question Link

我在可变长度的文本文件中有固定宽度的列数据，所以我想用制表符分隔数据.为此，我想使用 Powershell 读取文件，使用 Regex 表达式仅用制表符替换多个空格，保持行尾完整并将其输出到临时文件.然后我会将其重命名为原始名称.

I have fixed width column data in a text file that are of variable length, so I'd like to delimit the data with tabs. To do so, I want to use Powershell to read in the file, replace only multiple spaces with tabs using a Regex expression, keep the end of lines intact and output it to a temp file. I'll then rename it to the original.

我在网上搜索过，似乎只能找到一些零碎的东西.对此的任何帮助将不胜感激！

I've searched the web and only seem to be able to find bits and pieces. Any assistance with this would be greatly appreciated!
