expect and cron
I have the following expect script, which I want to run in cron. It fails however, very likely due to the fact that there's no /dev/tty available.

Code:
set timeout 30
spawn -nottycopy -nottyinit /usr/bin/ssh $hostname $command
match_max 100000
expect "password"
send -- "$password"
send -- "\r"
interact

I added the -nottycopy -nottyinit arguments in the hope that would cause spawn to not try to recreate /dev/tty but it didn't work. Also, switching of interact doesn't work. The code works on a command line.

Any ideas anyone?
