Expect script inside bash script optional statement

Question

Using: CentOS 6.2 BASH shell

My script is something along the lines of

#!/bin/bash
INSTALL_PATH="Enter install path"
CR="\n"
/bin/su root -c "/usr/bin/expect << EOF
spawn name.run
expect $INSTALL_PATH
send $CR
EOF; ... do more stuff..."

Now sometimes my name.run file asks "Would you like to uninstall?" how can I send this as an optional argument after the first send?

Answer 1

You can put multiple patterns inside an expect command

spawn name.run
expect $INSTALL_PATH
send \r
expect {
  {Would you like to uninstall?} {
    send yes\r
    exp_continue 
  }
  eof 
}

Take note that you send "\r" to "hit enter".

Also, the terminal word for a here-doc must appear by itself on a line -- it cannot be followed by "; more stuff"
