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.

Code:

echo "appended text" >> somebinary

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