Answer 1

Something like the following code snippet should work :

for (( i=0; i <= 5; i++ ))
#heredoc. the '-' is needed to take tabulations into acount (for readability sake)
#we begin our expect bloc
do /bin/usr/expect <<-EOD
    #process we monitor
    spawn test.sh
    #when the monitored process displays the string "[Y/n]" ...
    expect "[Y/n]"
    #... we send it the string "y" followed by the enter key ("\r") 
    send "y\r"
#we exit our expect block
EOD
done
