如何使用 Windows 命令行环境查找和替换文件中的文本? [英] How can you find and replace text in a file using the Windows command-line environment?

问题描述

我正在使用 Windows 命令行环境编写批处理文件脚本，并希望将文件中出现的某些文本(例如FOO")更改为另一个(例如BAR").最简单的方法是什么?有什么内置函数吗?

I am writing a batch file script using Windows command-line environment and want to change each occurrence of some text in a file (ex. "FOO") with another (ex. "BAR"). What is the simplest way to do that? Any built in functions?

推荐答案

这里的很多答案帮助我指明了正确的方向，但没有一个适合我，所以我发布了我的解决方案.

A lot of the answers here helped point me in the right direction, however none were suitable for me, so I am posting my solution.

我有 Windows 7，它内置了 PowerShell.这是我用来查找/替换文件中所有文本实例的脚本:

I have Windows 7, which comes with PowerShell built-in. Here is the script I used to find/replace all instances of text in a file:

powershell -Command "(gc myFile.txt) -replace 'foo', 'bar' | Out-File -encoding ASCII myFile.txt"

解释一下:

• powershell 启动 Windows 7 中包含的 powershell.exe
• -Command "... " 是 powershell.exe 的命令行参数，包含要运行的命令
• (gc myFile.txt) 读取 myFile.txt 的内容(gc 是 Get-Content 命令)
• -replace 'foo', 'bar' 只需运行替换命令将 foo 替换为 bar
• <代码>|Out-File myFile.txt 将输出通过管道传输到文件 myFile.txt
• -encoding ASCII 防止将输出文件转录为 unicode，正如注释所指出的

• powershell starts up powershell.exe, which is included in Windows 7
• -Command "... " is a command line arg for powershell.exe containing the command to run
• (gc myFile.txt) reads the content of myFile.txt (gc is short for the Get-Content command)
• -replace 'foo', 'bar' simply runs the replace command to replace foo with bar
• | Out-File myFile.txt pipes the output to the file myFile.txt
• -encoding ASCII prevents transcribing the output file to unicode, as the comments point out

Powershell.exe 应该已经是您的 PATH 语句的一部分，但如果不是，您可以添加它.它在我机器上的位置是 C:WINDOWSsystem32WindowsPowerShellv1.0

Powershell.exe should be part of your PATH statement already, but if not you can add it. The location of it on my machine is C:WINDOWSsystem32WindowsPowerShellv1.0

更新
显然现代 Windows 系统内置了 PowerShell，允许您直接使用

Update
Apparently modern windows systems have PowerShell built in allowing you to access this directly using

(Get-Content myFile.txt) -replace 'foo', 'bar' | Out-File -encoding ASCII myFile.txt
