[JSch-users] Multiple commands using a ChannelExec?

[Andrzej T. <an...@ch...>]

I've done an extended version of the Ant sshexec task which lets you nest multiple
commands to be executed on the remote host.

I keep the session open, but have been creating a new ChannelExec for each command
submission.  Problem with that is that your "environment" is not retained on the remote
host between individual commands.  For example, if I do two command, "cd .." and "ls -a"
the directory is no longer set to the parent by the time the ls is executed.

Is there a way to use a ChannelExec so that you can execute multiple commands, but not
have it reset you back to the beginning regarding the "environment"...sort of like a
normal telnet session?

I'm thinking of something like not creating a new ChannelExec each time.  Can you do a
connect(), disconnect() and another connect() on the same channel to do this?  Multiple
connect() calls without an intervening disconnet()?  Or something else?  Or maybe I can't
get there from here.

I looked at the code for Channel, ChannelSession and ChannelExec, but it's pretty poor
code, with zero comments, so on cursory inspection I'm not sure what it's doing.

Any/all assistance would be very much appreciated!

Thanks from a JSCH newbie.
