Read the documentation for whatever software package you are using to create your setup and see if they have support for file writing operations.

You are going to get mad skills. No, it won't make sense. But if you disagree, you need to explain the "requirement".

i have done something similar before.
"get the value by using directoryinfo.getfiles(*.bat)" or something like this" u need the path to the file here
this is from memory so there may be little mistakes but this is how to do.

C#

string batlocation=".bat location";
string battxt = String.Empty;

if (File.Exists(batlocation))
{
using ( var reader = new StreamReader(batlocation))
{      
         battxt = reader.ReadToEnd();
         //now in battxt u have everything that was in bat file
}
}

now u can use some string replace or search or regex to change the bat file.

then if you would like to write changes over just

do like this

C#

if (File.Exists(batlocation))
{
//move the old .bat file for backup 
File.Move(batlocation)
//this move command is probably wrong google for move files.

using ( var writer = new StreamWriter(batlocation))
{      
         battxt = writer.Write(battxt)
         //now you write back to new bat file with your chagnes in there

}
}
