Why use three commands when one will do?
LOL, because this looks damned complicated :
ssh $HOST 'awk '\''/^#.*root=/ { dev=$NF; sub("root=", "", dev); print
dev }'\'' /boot/grub/grub.conf'
Yes, I added a bit that wasn't in the original, namely the removal of
the "root=" text. Without that, it's a bit simpler:
ssh $HOST 'awk '\''/^#.*root=/ { print $5 }'\'' /boot/grub/grub.conf'
