Edit file in hex mode

In vim :%!xxd will apply xxd cmd to current file.

Let’s say we have a file with “HeX” in it. Open it in vim and do :%!xxd we got:

0000000: 4865 580a                                HeX.

• 0000000 must keep untouched
• 4865 580a can be edited
• HeX. must keep untouched

When you are done editing hex data just do :%!xxd -r and you can save it :w.
