How can I insert hex datas at a specific offset? more than 256?
I tried something like :
echo "00054cc0: 16c65206...5656c6c652eaa" | xxd -c 256 -r - myFile.bin
How can I do if I want to insert a long text or a text file here?

Stack Overflow is a site for programming and development questions. This question appears to be off-topic because it is not about programming or development. See [What topics can I ask about here](http://stackoverflow.com/help/on-topic) in the Help Center.

It's all about programing! It's modifying directly files from hexadump! – stef toto Nov 29 '17 at 21:55
