Executing a script

An SshScript will begin execution as soon as a connection is established with the SSH server. Therefore it is recommended that your SshScript be created and all tasks added before the Ssh.Connect method is invoked.

As an example the code example below will demonstrate how to automatically login to a SSH server, execute a command and logout. Some assumptions have been made about your shell prompt. Your shell prompt may differ although the fundamental process would be the same.

Example

[C#]

// create login credentials

SshParameters sshParams = new SshParameters(hostname,username,password);

// create new Ssh instance

Ssh ssh = new Ssh(sshParams);

// create new SshScript and associate with Ssh instance

SshScript script = new SshScript(ssh);

// create first task

SshTask task1 = new SshTask("$","ls -al","$");

// create second task

SshTask task2 = new SshTask("$","pwd","$");

// add tasks to script to be executed in order

script.AddTask(task1);

script.AddTask(task2);

// connect and execute tasks

ssh.Connect();

// wait until last task is complete

while(!task2.IsComplete) {

 Thread.Sleep(100);

}

// print out results of task1

Console.WriteLine(task1.Response);

// print out results of task2

Console.WriteLine(task2.Response);

// disconnect

ssh.Disconnect();

End While
