expect: when does a spawned process terminate?

mlnpscda
mlnpscda used Ask the Experts™
on
when an expect script spawns a process, say, telnet

spawn telnet $target

the script does its thing then exits.  Is the telnet session still hanging around? Or does it close when the script terminates?

Thanks!

I tend to find the session terminates when the session is closed.

telnet will close when the script finishes (because it gets end of file on its stdin).
In general the easiest way to terminate a spawned process is to exit the expect script; otherwise you have to "expect eof" "wait" and so on
