使用外档时避免换行 [英] Avoid line breaks when using out-file

问题描述

对于正在编写的PowerShell脚本，我感到有些沮丧.

基本上，我遍历文本文件以根据正则表达式模式数组检查每一行. 结果将通过管道传输到输出文件cmdlet，然后将其附加到另一个文本文件.

Get-ChildItem $logdir -Recurse -Include @('*.txt') | Get-Content | ForEach-Object { 
Select-String $patterns -InputObject $_ | Out-File $csvpath -Append -Width 1000 }

我的问题是我无法退出文件，以忽略它在$ csvpath后面的文件中创建的其他换行符(每行后三). 我可以使用.NET Framework类来实现相同的目的，但是我宁愿坚持使用纯PowerShell;-)

非常感谢您的帮助.

为什么不使用Add-Content?

gci $logdir -rec *.txt | gc | select-string $pattern | add-content $csvpath

您不需要指定宽度和-append开关，默认情况下文件大小不会加倍(尽管您可以指定编码)，而且空行似乎没有问题. /p>

I'm getting a little frustrated on a little PowerShell script I'm writing.

Basically I loop through text files to check every line against an array of regular expression patterns. The result gets piped to the out-file cmdlet which appends it to another text file.

Get-ChildItem $logdir -Recurse -Include @('*.txt') | Get-Content | ForEach-Object { 
Select-String $patterns -InputObject $_ | Out-File $csvpath -Append -Width 1000 }

My problem is that I can't get out-file to omit those additional line breaks it creates in the file behind $csvpath (three after each line). I could use .NET framework classes to achieve the same thing but I'd rather stick to pure PowerShell ;-)

Any help is greatly appreciated.

Why don't you use Add-Content?

gci $logdir -rec *.txt | gc | select-string $pattern | add-content $csvpath

You don't need to specify the width and -append switch, the file size is not doubled by default (although you can specify encoding) and it seems that there is no problem with the empty lines like you have.
