Hi Guys,

I do want to automate the creation of recovery keys on our mac environment and I do have some troubles with the expect of the spawn command. Details:

I need to expect the following string:

Enter a password for '/':

But I always end up getting the following information from the expect when running bash -x:

Enter a password for /:

My Code is:

expect -c " 
spawn `sudo fdesetup changerecovery -personal`
expect `Enter a password for ''''/'''':` {send $REC_PW
} 
sleep 1 exit
"

Any idea on what is going wrong here?

    I would probably use something like:

    #!/usr/bin/expect

spawn sudo fdesetup changerecovery -personal
expect "Enter a password for ''''/'''':" 
send "$REC_PW
"
interact

    Where is the $REC_PW variable value coming from?

    That all being said, I think you're supposed to enable it with a plist file ([https://derflounder.wordpress.com/2015/02/02/managing-yosemites-filevault-2-with-fdesetup/])(https://derflounder.wordpress.com/2015/02/02/managing-yosemites-filevault-2-with-fdesetup/)
