Lightweight bash utility to display dynamic system time to shell
Download 'clock' into /bin or /usr/bin directory and make it executable using cd /usr/bin chmod +x clock, make sure /usr/bin is in $PATH.
Alternatively, save it wherever you want and make an alias in ~/.bashrc. Something like alias clock='bash /path/to/file'
Type clock into your terminal and enjoy!
Ctrl-C to stop the clock.
You can modify clock's behaviour using switches. Check out clock -h for more info.
