[Mono-list] How to Run Linux Execute Command ">" and "&"

[cosy]

Hello Everybody!Im working in linux. I have a problem for you.When the button
clicked, I execute a linux command like "mpirun" in background even my mono
program closed after button clicked. However i have a problem with ">" and
"&" command.I want to get a program standard output line by line with live
time continuosly and put it in "regcm.out" syncronusly. But now i get the
output when the standartoutput finished. And when my program closed, i can
not get the outputs at all. I want to work it in background so i want to
execute ">" and "&" commands what can i do? My code is;	protected void
OnRunModelButtonClicked (object sender, EventArgs e)	{			SaveFile ();					
string regcmMPI = Tools.regCmBinPath + "regcmMPI";			string CoreSelection =
CoreSelectionTextview.Buffer.Text;*			string mpirunCode= (CoreSelection + "
" + regcmMPI + " " + Tools.projectPath + "XRegCM.in" + ">>regcm.log 2>&1");*						
*Tools.ExecuteOperation executer = Tools.ExecuteAsync;			
executer.BeginInvoke("mpirun", " -np " + mpirunCode, Tools.mpirunPath,
Tools.Callback, executer);*						}				}Tools. ExecuteAsync / Execute;	public
static int Execute(string exe, string args, string workingDirectory, ref
string standartOutput, ref string standartError, bool isAsync)	    {		
standartOutput = "";			standartError = "";	         ProcessStartInfo oInfo =
new ProcessStartInfo(exe, args);	         oInfo.UseShellExecute = false;	        
oInfo.CreateNoWindow = true;		         oInfo.RedirectStandardOutput = true;	        
oInfo.RedirectStandardError = true;			 if(workingDirectory != "")			 {			 
oInfo.WorkingDirectory = workingDirectory;			 }						int exitCode = -1;					
try			{		         Process proc = System.Diagnostics.Process.Start(oInfo);		        
proc.WaitForExit();		         exitCode = proc.ExitCode;								
System.IO.StreamReader sReader =	proc.StandardOutput;				 standartOutput =
sReader.ReadToEnd ();				 sReader = proc.StandardError;				 standartError =
sReader.ReadToEnd ();		         proc.Close();			}			catch(Exception exp)			{			
if(!isAsync)				{					MessageBox.Show (exp.Message);					MessageBox.Show
(exp.StackTrace);				}				else				{					standartError += "\n Exception
Message : " + exp.Message;					standartError += "\n Exception Stack Trace :
" + exp.StackTrace;				}			}										         return exitCode;	    }
