chexedit

Full screen text mode Hex editor using the [n]curses library

Hexedit is a Curses based Hex editor. Unlike a text editor, which is used for editing text documents in the desired language, hexedit lets you edit any file as its byte for byte representation. It can even let you view and edit your fixed disks on your Linux system. This is not ideal for writing a letter or writing c code, but there are my times when this is ideal: * Editing binary executables. * Editing your fixed disks (i.e. /dev/xyz) * Checking the output of a Program's binary data file. * Any place you might use od(1) but need more power. Compare more vs less.
