Tail has a built in capability to follow logs tail -f /var/log/dmesg

nobody can be a sysadmin until he discovered "tail -f" ;-)

but the output from watch "command" is so much easier to read...

also, /var/log/dmesg stops being written to after booting (at least in ubuntu) so the output would not be the same.
