推荐答案

在本机 Windows 安装中，您可以使用批处理 (cmd.exe) 或 vbscript，而无需获取外部工具.这是 vbscript 中的一个示例:

On a native Windows install, you can either use batch(cmd.exe) or vbscript without the need to get external tools. Here's an example in vbscript:

Set objFS = CreateObject("Scripting.FileSystemObject")
strFile = "c:	estfile.txt"
Set objFile = objFS.OpenTextFile(strFile)
Do Until objFile.AtEndOfStream
    strLine = objFile.ReadLine
    If InStr(strLine,"ex3")> 0 Then
        strLine = Replace(strLine,"ex3","ex5")
    End If 
    WScript.Echo strLine
Loop    

另存为 myreplace.vbs 并在命令行中:

Save as myreplace.vbs and on the command line:

c:	est> cscript /nologo myreplace.vbs  > newfile
c:	est> ren newfile file.txt
