Powershell脚本进入目录中的文本文件并替换字符 [英] Powershell script for going into texts files within a directory and replacing characters

问题描述

早上所有的，

我试图找出如何进入一个目录中的许多文本文件，并用下面的代替字符：

/ p>

'BS'='\'

'FS'='/'

'CO'='：'

到目前为止我所能达到的是：

 （get-content C：\ users \x\desktop\info\ * .txt）| foreach-object {$ _ -replacebs，\} | set-content C：\ Users \x\desktop\info\ * .txt 
  

我有6个文本文件，所有文本都带有一行文本，上面的脚本将文本行复制到所有文本文件中。所以我最终得到的是6个文本文件，每个文本有6行，我需要6个文本文件，1行原文。

如果这是有道理的，有没有人有任何指示呢？

解决方案

Y应该这样做：

  Get-ChildItem C：\users\x\desktop\info\ * .txt | ForEach-Object {（Get-Content $ _。PSPath）| Foreach-Object {$ _-替换bs，\ - 替换fs，/ - 替换co，：} | Set-Content $ _。PSPath} 
  

原因是您的行为不像您期望的那样，是因为你使用get-content从字面上把所有内容从所有文件中取出。这就像所有文件中所有文本的字符串连接一样。

您首先必须获取文件列表，然后将其转换为foreach文件以获取每个文件的内容，然后替换你想要替换的东西。

Morning all,

I'm trying to work out how to go into a number of text files within a directory, and replace the characters with the following:

'BS' = '\'

'FS' = '/'

'CO' = ':'

What I managed to get to so far is:

(get-content C:\users\x\desktop\info\*.txt) | foreach-object {$_ -replace "bs", "\"} | set-content C:\Users\x\desktop\info\*.txt 

I have got 6 text files, all with a line of text in them, the script above copies the line of text into all the text files. So what I end up with is 6 text files, each with 6 lines of text, I need 6 text files with 1 line of original text.

If that makes sense, does anyone have any pointers on this?

解决方案

YThis should do the trick:

Get-ChildItem C:\users\x\desktop\info\*.txt | ForEach-Object {(Get-Content $_.PSPath) | Foreach-Object {$_ -replace "bs", "\"  -replace "fs", "/"  -replace "co", ":"} | Set-Content $_.PSPath}

The reason yours wasn't acting as you expected it to, is because you where literally taking all the contents out of all files using get-content. This acts like a string concatenation of all text in all files.

You first have to get a list of files, then pipe that into a foreach to get the contents per file, to then replace what you want replacing.
