Re: [JSch-users] invoke shell script on remote Linux machine using JSch without waiting for the STDOUT/ERR from the shell

[william b. <wba...@gm...>]

I think you need STDOUT/STDERR in order to know of the command ran or 
not. I would use the ChannelShell instead of exec and then run your 
script. If you receive the prompt then you know your command executed 
and you can terminate your session. Found a decent example here:
