I am using psexec.exe to install some software on a large amount of computers. I would like to be able to catch the %ERRORLEVEL% (or its c# equivalent) and write them to a TXT file. ( cmd.exe exited on 6440-nbpb00f51w with error code 0.)
After extensive research, I am finding several possibilities. My end-goal will be to have a .CSV file. Each row would have the computer name and the output of the psexec command. Using this data I will be able to determine which computers the update was successful on.
string[] pcnamearray = new string[] {"COMPUTERNAME1", "COMPUTERNAME2"};
foreach (string i in pcnamearray)
{
Process p = new Process();
string psexeclaunch = "psexec.exe";
p.StartInfo.FileName = psexeclaunch;
p.StartInfo.RedirectStandardOutput = false;
p.StartInfo.UseShellExecute = true;
p.StartInfo.CreateNoWindow = false;
string arg = "/silent";
p.StartInfo.Arguments = @" -i \\" + i + @" -u mydomain\admin -p mypassword -h -e cmd.exe /c start \\networkserver\sw\myfile.exe" + arg;
p.Start();
}
I am not here looking for someone to write the code for me. I am here to ask people for their advice, or past experiences with this. I know there are several different methods available. Ideally, I would prefer to have a short sweet line for each result, but if i have to take the entire output and use macros to shave them down to a more readable form, that is fine too.
So far, I have tried:
Console.WriteLine(p.StandardOutput.ReadToEnd());
And...
System.IO.File.WriteAllLines(@"C:\Users\areu2447\Desktop\UpdateDAT\Final\out.txt", lines);
And...
FileStream filestream = new FileStream(@"C:\Users\areu2447\Desktop\UpdateDAT\Final\out.txt", FileMode.Append);
var streamwriter = new StreamWriter(filestream);
streamwriter.AutoFlush = true;
Console.SetOut(streamwriter);
Console.SetError(streamwriter);
The last one seems to me like the best one but cannot seem to get it to work. I have tried including it in my foreach loop, but file is in use by another process, so after looking into it i found that it needed to be on its own. Even with it alone, i still cannot get it to work.
Please help/advise!
I was able to get it to actaully modify my TXT file, even though there was nothing added to it, by using the following:
System.IO.StreamReader reader = p.StandardOutput;
String sRes = reader.ReadToEnd();
StreamWriter SW;
SW = File.CreateText(@"C:\Users\areu2447\Desktop\UpdateDAT\Final\out.txt");
SW.WriteLine(sRes);
SW.Close();
Console.WriteLine("File Created Successfully");
reader.Close();
