Trying to run `bash -c ""` command with Process.Start/ShellExecute

Bash-ShellExecute.cs

// works in LinqPad
void Main()
{
	ExecuteCommandLine("wt");  // works - this is resolved
	
	ExecuteCommandLine("bash");  // The system cannot find the file specified
	
	// actual command line I'm trying to fire
	ExecuteCommandLine("bash -c \"cd /mnt/c/projects/Test/jekyll/help; bundle exec jekyll serve\"");
}



public void ExecuteCommandLine(string fullCommandLine, 
				   string workingFolder = null, 
				   int waitForExitMs = 0, 
				   string verb = "OPEN",
				   ProcessWindowStyle windowStyle = ProcessWindowStyle.Normal)
{
	string executable = fullCommandLine;
	string args = null;
	
	if (executable.StartsWith("\""))
	{
		int at = executable.IndexOf("\" ");
		if (at > 0)
		{			
			args = executable.Substring(at+1).Trim();
			executable = executable.Substring(0, at);
		}
	}
	else
	{
		int at = executable.IndexOf(" ");
		if (at > 0)
		{
			
			if (executable.Length > at +1)
				args = executable.Substring(at + 1).Trim();
			executable = executable.Substring(0, at);
		}
	}

    // this also doesn't work
	// ShellExecute(IntPtr.Zero,verb,executable,args,workingFolder,(int) windowStyle);

	var pi = new ProcessStartInfo();
	pi.UseShellExecute = true;
	pi.Verb = verb;

	{
		if (waitForExitMs > 0)
		{
			if (!p.WaitForExit(waitForExitMs))
				throw new TimeoutException("Process failed to complete in time.");
