Modifying contents of the file in shell script

Hello all,
I have a Kconfig file that looks like something below ...
================================
Code:
menu "Application type"
                config GUI_TYPE_STANDARD
                        bool "Standard Application"

        source "cfg/config/std.in"
        source "cfg/config/cust.in"
        source "cfg/config/lang.in"
        source "cfg/config/type.in"
endmenu

=================================


I want to modify this file in shell script so that it should look like below ..

=================================
Code:
        source "./non_Profile/app/std.in"
        source "./non_Profile/app/cust.in"
        source "./non_Profile/app/lang.in"
        source "./non_Profile/app/type.in"

==================================


Thanks in advance !!!

Dear Friend,
I am new to shell scripting and "awk" so not able to find the issue but it is deleting contents of the file.

Test this (works fine for me)
Code:
echo 'menu "Application type"
config GUI_TYPE_STANDARD
bool "Standard Application"

source "cfg/config/std.in"
source "cfg/config/cust.in"
source "cfg/config/lang.in"
source "cfg/config/type.in"
endmenu' | awk '/^source/{sub("cfg/config","./non_Profile/app",$0);print}'

Code:
source ./non_Profile/app/std.in
source ./non_Profile/app/cust.in
source ./non_Profile/app/lang.in
source ./non_Profile/app/type.in

Dear Jotne,
When I run "awk" on the output of echo (it's same way you have shown), its working fine for me. But what i want is, whatever is there in echo command is part of file and I want to run "awk" on the file. In this way its not working.
What I want is ....
Code:
awk '/^source/{sub("cfg/config","./non_Profile/app",$0);print}' my_file

where my_file contents
Code:
menu "Application type"
config GUI_TYPE_STANDARD
bool "Standard Application"

source "cfg/config/std.in"
source "cfg/config/cust.in"
source "cfg/config/lang.in"
source "cfg/config/type.in"
endmenu
