Top Hex Editors for Linux Systems

Hex editor lets you view/edit the binary data of a file – which is in the form of “hexadecimal” values and hence the name “Hex” editor. Let’s be frank, not everyone needs it. Only a specific group of users who have to deal with the binary data use it.

Let me give you an example if you have no idea what it is. Suppose you have the configuration files of a game; you can open them using a hex editor and change certain values to have more ammo/score, and so on. To learn more about Hex editors, you should start with the Wikipedia page.

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 the file, while a hex editor represents the physical contents of the 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 commonly 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 the 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.

1. Xxd Hex Editor

Most (if not every) Linux distributions come with an editor that allows you to perform hexadecimal and binary manipulation. One of those tools is the command-line tool – xxd, which is most commonly used to make a hex dump of a given file or standard input. It can also convert a hex dump back to its original binary form.

2. Hexedit Hex Editor

Hexedit is another hexadecimal command-line editor that might already be preinstalled on your OS. Hexedit shows both the hexadecimal and ASCII view of the file at the same time.

3. Hexyl Hex Editor

Another useful tool for examining binary file is hexyl, is a simple hex viewer for Linux terminal that uses a colored output to determine different categories of bytes.

The view of hexyl is split into three columns:

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

The installation of this hex viewer is different for different operating systems, so it is recommended to check the readme file in the project to see the exact installation instructions for your OS.

4. Ghex – GNOME Hex Editor

Ghex is a graphical hex editor that lets users edit a binary file in both hex and ASCII format. It has a multilevel undo and redo mechanism that some may find useful. Another useful feature is finding and replacing functions and converting between binary, octal, decimal, and hexadecimal values.

5. Bless Hex Editor

One of the more advanced hex editors in this article is Bless, which is similar to Ghex, it has a graphical interface that allows you to edit large data files with a multilevel undo/redo mechanism. It also has customizable data views, a find-replace feature, and multi-threaded search and saves operations. Multiple files can be opened at once using tabs. Functionality can also be extended through plugins.

6. Okteta Editor

It has low memory consumption and can view multiple files at once. Since it has so many features and benefits, you may want to review them all on the wiki page or the official wxHexEditor website.

8. Hexcurse – Console Hex Editor

Hexcurse is a Ncurses-based hex editor. It can open, edit, and save files within a friendly terminal interface that allows you to go to a specific line or perform a search. You can easily toggle between hex/decimal addresses or switch between hex and ASCI windows.
