Inline searc and replace inside file
Hello,
I have a text file that i want to redirect into a new file , searching and replacing certain string during the opertaion.
This should be done using shell script , so it should not be interactive.
The script should get four parameters :
source file
target file
source string
target string

For example :

source file = a.txt
target file = b.txt
source string = apple
target string = banana

Sorce Text file a.txt contain:
=================
Hellow apple

target text file should contain the following result
=======================================
Hellow banana

Thanks
