Re: attaching a terminal to 'join' another?
The next-best is to use the /usr/sbin/watch command to attach to an existing tty and see its screen output. You'll need to rebuild your kenel and add the snp device (or load it as a module). not necessariliy build new kernel sudo kldload snp will do also ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Is this possible? The best solution is to install the sysutils/screen port and run your build process in a window under that. Then you can attach to that screen session from any number of other logins (at the same time even). As a side-effect, screen will protect you from accidental terminal disconnections (if you close your xterm or ssh disconnects on you, screen will detach the session and it will run headless until you reattach to it). The next-best is to use the /usr/sbin/watch command to attach to an existing tty and see its screen output. You'll need to rebuild your kenel and add the snp device (or load it as a module).
