unlimited commanding

This one is pretty simple trick..
in ubuntu whenever i want to use internet i use wvdial.
it is a simple tool to make a connection by ppp dialing.
i'm using really a bad network.. :(
it will sometimes automatically disconnect..
morever it will not make my connection quickly.. i have to use
the command
sudo wvdial
repeatedly.. sometimes more than 7 or 8 times..

so this simple command help me to resolve this problem.

we have to use while loop to do this command infinite times.

just type



while :
do
  command
done

or

while : ; do command; done

on the above line simply put your desired command to do the magic.

i use wvdial..

sudo while : ; do wvdial; done

now i'm free from typing that command.. don't care about disconnection it will
automatically redial
