how to execute a terminal command in c#

Question

I read many post, from them there is this one

c# - Opening the terminal process and pass commands?

I do the exact same thing in my code

Process proc = new System.Diagnostics.Process ();
proc.StartInfo.FileName = "/bin/bash";
proc.StartInfo.Arguments = "-c \" " + command + " \"";
proc.StartInfo.UseShellExecute = false; 
proc.StartInfo.RedirectStandardOutput = true;
proc.Start ();

where command = export DISPLAY=:0.0

and it goes to my catch, "pplicationName='/bin/bash', CommandLine='-c " cd .. "', CurrentDirectory='', Native error= The system cannot find the file specified."

what do I do differently? even if I try to juste set command = "cd .." it doesn't work

"goes to your catch", can you tell us what the error is that you get in the catch? Specifically the type of error and the message that it contains. — Ron Beyer

Where you are setting StartInfo.FileName - I notice that's a relative path not a full path. Have you tried specifying the full path to the exe just in case it's not resolving the correct path which is causing the problem? — Darrell

You should probably try setting the full path the executable.

proc.StartInfo.FileName = "C:/SOMEPATH/Bash.exe";

I'm assuming as you are specifying a relative path, it's not resolving it. Possibly because you aren't setting a working directory for the process so it's current dir and the current dir you think it has, are different.

@CherrysaHerrim there is no bash shell on Windows unless you install one. Also, there is no benefit from doing a cd command in a shell (it won't affect the running application's current working folder).
