Have you looked at your shell's man page? Or at other posts in this or other forums? Or any of the many shell tutorials on the Web?

This implements an infinite loop. It will continue looping until you execute a break statement:

Code:
while true
do
   : do whatever
done

You cannot rely on its working, which is why it is better to use printf.
can you give me one reason why can't we relay on its working??

Because it is not supported on many systems.

On Linux with bash or ash or dash or pdksh or ksh93, or on FreeBSD with sh or ksh or bash, or on NetBSD with bash or sh or ksh, or on SunOS with sh or ksh, etc., you get this:

Code:
$ echo "qwerty\cuiop"
qwerty\cuiop
$

Run the script and see what it does. If it does what you want, it works. If it doesn't, fix it. If you have trouble fixing it, come back here and ask for help about the specific part that is not working.

Post only the part of the code that is not working. Post any error messages you get. (Cut and paste them; do not retype them.)
