=>Hi
=>
=>If i am locally on a box the following works fine
=>
=>ROOTDEV=`cat /boot/grub/grub.conf | grep "^\#.*root\=" | awk '{print $5}'`
=>
=>but if i put this into a script to run from another host it fails eg
=>
=>ssh $HOST 'ROOTDEV=`cat /boot/grub/grub.conf | grep "^\#.*root\=" | awk
=>'{print $5}'`'
=>awk: cmd. line:1: {print
=>awk: cmd. line:1:       ^ unexpected newline or end of string
=>
=>seems the space in the print $5 upsets things - anyone know how to escape this
=>space out so it will work?
=>
=>thanks

ROOTDEV=$(ssh $HOST awk < /boot/grub/grub.conf '/^#.*root=/ {print $5}')

You had embedded single quotes. Also, you didn't need cat or grep. Also, 
the = sign and the # don't need to be backquoted. Also, the output of awk 
being assigned to ROOTDEV was simply being dropped.
