There are several ways to view the binary:

Method One: Hexdump

Apt-get Install Libdata-hexdumper-perl

After installation, you can hexdump the your_binary_file directly.

You can also use the HD command directly instead of Hexdump.

If you want to look slowly: HD Your_binary_file | More

Method Two:

Vim can be used to view and edit binary files

Vim-b Egenea-base.ko Plus-b parameter, open in binary

Then enter the command:%!XXD-G 1 switch to hexadecimal mode display

You can then modify the 16-character characters as you would a text file, with/find the specified offset, and so on. Modifying the ASCII character to the right should not be valid. After the modification is done:%!xxd-r switch binary mode, then: Wq Save to exit. In this vim inside such editing is still very convenient, note must:%!xxd-r switch back after the save line.

Method Three. Linux also has 16 GUI tools for editing

Jeex (http://www.hds619.net/jeex.php)

Ghex

Bless (Bless is a Hex Editor for gtk# http://home.gna.org/bless/)

UltraEdit

Two binary comparisons can be made using Vimdiff.

Vimdiff should still be useful, similar to the Windows platform WinDiff

VIM-BD Base.ko Base2.ko

After opening, you can display two files in two windows.

CTRL + W +L switches the input focus to the right window, activates the right window and then enters the command for the right window.
:%!xxd-g 1 Switch to a 16-byte pattern of binary
CTRL + W +H switch the input focus to the left window
:%!xxd-g 1
] + C to find the last different point
[+ C finds the next different point
