On Windows machines there are lots of third party editors available to edit a binary file.

Any idea how can I edit a binary file on Unix system?

Best Solution

In vim You can type :%!xxd to turn it into a hexeditor. :%!xxd -r to go back to normal mode. xxd is shipped in a vim installation.

See here for some remarks about editing binary files with vim (boils down to :set binary to avoid trouble, use only the "R" or "r" command to change text, don't delete characters).
