Help: Command line rotating line

[Chaman Singh Verma]

Hello,

I am not quite sure if this is the place to ask some specific question about
linux/unix functionality. So if it
is not the right place, please ignore this mail.

I have seen many software that uses command line rotating line to indicate
wait for example

Processing Sequence ....  |    This | line keeps on rotating

and other example

Current iteration number . #  ( In this # keeps on changing on the screen )

Can someone tell me how it is done ? What software I must use which is
available on ubuntu ?
