Top Hex Editors for Linux

In this article, we are going to review some of the best hex editors for Linux. But before we start, let’s look at what a hex editor really is.

What is Hex editor

In simple words, a hex editor allows you to examine and edit binary files. The difference between a regular text editor and the hex editor is that the regular editor represents the logical content of file, while a hex editor represents the physical contents of file.

Who use Hex editor

Hex editors are used for editing individual bytes of data and are mostly used by programmers or system administrators. Some of the most common used cases are debugging or reverse engineering binary communication protocols. Of course there are many other things you can use hex editors – for example reviewing files with unknown file format, performs hex comparison, reviewing program memory dump and others.

Most of these mentioned hex editors are available to install from the default repository using your distribution’s package manager, like so:

# yum install package       [On CentOS]
# dnf install package       [On Fedora]
# apt install package       [On Debian/Ubuntu]
# zypper install package    [On OpenSuse]
# pacman -Ss package        [on Arch Linux]

If no package available, head over to the website of each tool where you will get the standalone package for download and installation procedures, along with details on dependencies.

The view of hexyl is split in three columns:

  • Offset column to tell you how many bytes into the file you are.
  • Hex column, which contains the hexademical view of the file. (Note that there is a splitting line in between)

    thanks hexedit is exactly what I needed.

    Hexer in the screenshot is not the hexer this post is describing. And the URL is also wrong. Both URL and screenshot are for the C#-based GUI program, while the description is about C-based console one.

    Emacs is by far the best hex editor on the planet since you get a full featured editor too. Easily switch modes to find funky characters and edit in hex then switch back to ASCII for example.
