Working with command line interface in shell can be fun is you learn some tricks.
One of such tricks is using beautiful coloriser: ccze

It can colorise everything - try

sudo tail -f /var/log/messages | ccze -A
dmesg | ccze -A | less -R
df -hT | ccze -A
ls -lh | ccze -A
watch -d --color 'df -h | ccze -A'

So much nicer!
