Put a console clock in top right corner

This puts a clock in the top right of the terminal. This version doesn't use tput, but uses escape codes

A nice way to use the console in full screen without forget the current time.

you can too add other infos like cpu and mem use.

while true; do tput sc; tput cup 0 $(($(tput cols)-74)); w | grep load; tput rc; sleep 10; done &

Gives not only date but also some interesting status about the System

Know a better way?

If you can do better, submit your command here.

What others think

very nice tips, buf if someone only want to show system load information, then awk '{print $1,$2,$3}' /proc/loadavg is the key.

on my mac terminal, it shows the time, but cursor gets to the end of time, and never comes down!!!

I dont have a mac to test it. works fine in linux. youll have to check the escape sequence for saving and recalling the cursor position in mac os
