Script to execute command to get info from multiple servers

view story

http://www.unix.com – Hi, I want to collect info from a no. of servers whether there grub.conf contain "elevator" parameter or not. What I want is Code: sudo cat /etc/grub.conf | grep -q "elevator=noop"; echo $? If output is "0", I want name of that host in a file called "present" if its not "0", I want that hostname in a file called "not-present". Now, Password less key authentication is something I can not do as of now. I am okay with specifying password in script. Can someone please help me achieving this? (HowTos)
