Top Hex File Editors in Linux

Binary files are machine readable files that are used to store software packages and utilities. Generally, software developers write programs in human readable languages such as Python, C/C++, Java, etc. and convert their source code into binary files that are directly executable. Sometimes you may need to update the binary file if you don’t have access to original source code that was used to create the binary file. Since binary files consist of only 0 & 1 it is difficult to directly edit them. One of the ways to overcome this problem is to change the hexadecimal representation of your binary file, using a hex editor. In this article we will look at some of the top hex editors in Linux.
