I have a text file (...config.txt) containing 2 lines which looks like:

Preamp: -4 dB

Include: surround.txt

I need to change "surround" to "headphones" in that config file. I really need to make 2 batch files. One for "headphones" and one for "surround".

The config file in question is a file related to EqualizerAPO that calls a separate file containing EQ settings for a particular listening environment. In the example above, "surround". However, there can be many others. That config file, when saved, automatically triggers the EQ settings it's calling under the "include" line. The reason I need this is because, if I need to change the listening environment to something else, I need to browse to the directory, open the config.txt file, edit the "Include"
section to my needs, then save. It becomes tedious when I have to change it when the need arises. I really need a one-click solution. Any help would be greatly appreciated. Thank you!

EDIT:

The directory (containing that "config.txt" file referred to earlier):

C:Program FilesEqualizerAPOconfig

contains 2 types of text files: EQ settings files (e.g. headphones, surround, theater, etc. Basically the files that users create and export in TXT format via software called Room EQ Wizard. We'll call them "reference" files.) The other is the actual single config file that EqualizerAPO uses to determine which "reference" file it needs to use and adjust it's EQ settings accordingly. EqualizerAPO attaches itself to the system effect infrastructure as an Audio Processing Object. All I need is a simple solution that would allow me to change the line "Include: surround.txt" to whatever other EQ file I need to use at that time. I am constantly switching between EQs, hence my coming here. If possible, I'd like to be presented with a list of choices.

For example:

Select from the following equalizers:



1. Headphones

2. Surround

3. Theater

4. ***

5. ***



Enter the number:_

And then exit when the number is chosen.

Ideally, it'd be nice to have a very minimal application of some sort running in the taskbar that allows a one-click solution, removing the use of batch files entirely. However, that is not a necessity. Batch files are fine for the time being.

See if this helps. I had this from when I needed to perform a search and replace on an XML file. The strings, as long as you enclose them in double-quotes, can have special characters such as greater than and less than (used as redirection by scripts, ignored here). If you don't like the usage of variables to define the files you want to modify, you could make them into arguments which you could pass to the script. But then you would have to change the logic to shift the parameters unless you explicitly say "parameter 1 is the file to be changed, parameter 2 is the string to be found, etc..."

Hope this helps someone. Windows XP or higher is required.

This should do the trick:

$filepath = "C:Program FilesEqualizerAPOconfigconfig.txt";

$equalizer = "";

$equalizers = @("Headphones","Surround","Theater");  # Add all options here.



if( -not (test-path $filepath))

    }

    elseif($equalizers -contains $args[0])

    {

        $equalizer = $args[0];

    }

    else

    {

        Write-Host "Invalid argument";

        exit(1);

    }

}

Save as filename.ps1 and create a bat file named filename.cmd and place them both somewhere in your PATH, that way you can run the script by typing "filename" in either windows start menu or run.

paste the following in the bat file:

@echo off

if [%1]== goto none

powershell "& '%~dp0filename.ps1' '%1'"

goto end

:none

powershell "& '%~dp0filename.ps1'"

:end

PS: if you havent before be sure to enable running of powershell scripts:

powershell "set-executionpolicy remotesigned"
