使用PowerShell从文本文件中删除空行 [英] remove empty lines from text file with PowerShell

问题描述

我知道我可以使用:

gc c:\FileWithEmptyLines.txt | where {$_ -ne ""} > c:\FileWithNoEmptyLines.txt

以删除空行.但是我如何用'-replace'删除它们?

to remove empty lines. But How I can remove them with '-replace' ?

推荐答案

我在这里找到了一个不错的衬板>>

I found a nice one liner here >> http://www.pixelchef.net/remove-empty-lines-file-powershell. Just tested it out with several blanks lines including newlines only as well as lines with just spaces, just tabs, and combinations.

(gc file.txt) | ? {$_.trim() -ne "" } | set-content file.txt
