Problem

There are numerous third-party editors for editing binary files on Windows PCs.

Is there any way I can edit a binary file on a Unix system?

Solution #1

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.

For some notes on editing binary files with vim (boiled down to: set binary to avoid difficulty, modify text only with the “R” or “r” command, don’t delete characters), see here.

If you’re an Emacs user, check out this tutorial on how to edit a binary file with Emacs.

GNOME utilities ghex2 can also be used. The automated hex-to-ASCII conversion is on the side, and the various character/integer decodes are at the bottom. (image courtesy of googlepages.com)
