Question: I'm having a issue trying to write input to linux process. Here the code goes:

```
        System.Diagnostics.Process process = new System.Diagnostics.Process();
        process.StartInfo.WorkingDirectory = "'/home/"+user+"/pacotes/"+nome_pacote.Text+"-1.0/'";
        process.StartInfo.FileName="dh_make";
        process.StartInfo.Arguments="-n -s";
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardInput = true;
        process.Start();
        Thread.Sleep(3000);
        process.StandardInput.WriteLine();

```

And here goes the error:

Answer: 
One other possibility is that the binary that you're launching is a dangling symlink. Check if the binary exists or is a symlink pointing to a valid binary.
The path you are trying to write too can't be written too.
" /home/vinholi/Ubuntu One/Uso do linux em flash drives/Programa gerador de .deb/GeradorDeb/GeradorDeb/bin/Debug/"

Looks like its a usb drive. Check the following:

1. Its not readonly.
2. Its not been mounted readonly.
3. The usb drive is not out of space.
