This expect script would be called from a shell script, and would ssh to the host passed as an argument (argv), perform the command specified, and disconnect. (Thanks, Tiger O.)
#!/usr/bin/expect
set timeout 1
set cmd {uname -a}
spawn ssh root@$argv
expect_after eof { exit 0 }
## interact with SSH
expect "yes/no" { send "yes\r" }
expect "password:" { send "rootpasswd\r" }
expect "# "
send "$cmd\r"
expect "$cmd\r"
expect "(.*)\r"
send "exit\r

send "exit\r need " in the end of the line
@cristian -- I know. But, you can always use a wrapper script in bash, possibly calling expect within a loop, to pass in any desired commands.
I've not looked lately, but surely there are some more flexible alternatives to expect... I'm thinking that this could be done easily enough with python....
@cristian: Expect already supports command line parameters, see here:
