如何使用JSCH发送CTRL + C？

Question

I'm using jsch ChannelShell to send commands to a remote system, but I can't send special commands like ctrl+c . I tried many things, but have no success.

Any help would be appreciated.

Answer 1

You can simply send a signal. In your case it will be 2 which corresponds to CTRL+C :

channel.sendSignal("2"); // sends (CTRL+C) signal

You can find list of Unix signals here .

Answer 2

I think, i figured out my fault. Cat and grep(and those type of commands) commands are one shot commands. They are not continuous. So I can't interrupt those commands. I have to stop listening stream to stop printing outputs.

Answer 3

if you want to terminate an operation like tail

Example -    BufferedReader reader = new BufferedReader(new InputStreamReader(ce.getInputStream()));
         OutputStream out=ce.getOutputStream();
out.write(3); //terminate the tail command

 out.flush();
