How to insert a string into a binary file
 

I want insert actual string into binary file, not the acsii value of the string

Its kind of xxd -r, but I am not getting intended result.
how can i do that ?

What exactly are you trying to accomplish? Adding anything to a binary file will likely corrupt the file and make whatever program that reads the file unable to read it.

You can append text to any file with the >> shell operator. but again your file will be corrupt.

You can probably get away with replacing text in a binary so long as the text is the same length before and after.
