使用动态值从模板txt文件输出文本

Question

I have a template txt file (example):

test_asd = value
this is the end of the file

From which I need to create other text files with different values in the place of value

I'm writing a program to use this in C# (using a child process cmd.exe and commands)

I have tried setting an environment variable but the output is not different from the original template file.

test.txt:

test_asd = %VALUE%
this is the end of the file

C#:

Environment.SetEnvironmentVariable("VALUE", "test");

Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "cmd.exe";
psi.UseShellExecute = false;
psi.CreateNoWindow = true;
psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = true;
p.StartInfo = psi;

p.Start();

p.StandardInput.WriteLine("type test.txt");
p.StandardInput.WriteLine("exit");

p.WaitForExit();

string output = p.StandardOutput.ReadToEnd();
Console.WriteLine(output);

Console.ReadLine(); // wait for 'Enter' to exit

Is there a way to do this?

Answer 1

I figured it out, here is the command:

type test.txt | sed.exe -e "s/\${value}/test/"

using UnxUtils
