how to get some sort of graphics using shell scripts?

[wrapster]

Hi all,
I would like to know how to have graphics embedded using shell scripts...
I mean simple =========>
or ---------> would do...
The main idea here is for every element of the bar to move for every % completion of data.....

I tried echo under a for loop ,but it was not giving me o/p that i could use?

eg:,
lets say that i want to install a pkg, a huge one...now for every % of the installation completed i would like to have "===>" ,move one step ahead....

If this is difficult to incorporate then i woudnt mind having a regular % counting itself (with numericals)

Thanks

Here's an example:

#!/bin/bash

typeset -i _ct
_ct=0
_strg=""

while [ $_ct -lt 10 ]
    do
        _ct=_ct+1
        _strg="*${_strg}"
        echo -e "\r${_strg}\c"
        sleep 1
    done
echo

Look at the manpage for echo for the explanations of \r & \c.
