hod is a very simple, nice little hexadecimal and octal data dumper. It is very useful when dealing with binary data. I wrote it long long time ago, because I did not like the complexities and the output format of od and such programs. I hope you will find it useful.
Suggestions, bug reports are always welcome.
hod v1.8
https://www.muquit.com/
usage: ./hod [options] <filename>
Where the options are:
-v : show version information
-h : show this help
-i : output C header file
-g : output golang byte array
-o : dump in octal
-8 : show as block of 8 bytes
-x str : convert a hex input to decimal
-d : show offsets in decimal
-s : show identical output lines
-r : reverse hod hexdump to binary
-w : reverse regular hex bytes to binary
If no filename specified, it will read from stdin
Example:
$ hod file
$ hod < file
$ cat file | hod
$ cat file | hod -
$ hod < file
$ hod -o file
$ echo"hello"| hod
$ echo -n "hello"| hod
$ hod -x 1c0
1c0 : 448
$ echo"0a 01 ff ef 0b"| hod -w > bin.bin
$ hod bin.bin | hod -r > bin_again.binThe latest version is 1.8.
Please look at ChangeLog for details.

Look at icon_example/ directory for an example how a 16.x16 PNG file is converted to Go byte array to use as an icon for the systray.
Pre-compiled binaries for Windows and Ubuntu are available from Releases page
A pre-built Debian package is available. To install the package, type
sudo dpkg -i hod_1.8-ubuntu_amd64.deb
To remove the package, type:
sudo dpkg -r hod
Go to the source directory and type:
$ sh ./configure
$ make clean
$ make
# make install
or
$ sudo make install
This time I used MING64 (Sep-17-2025) to compile. To compile, just like Linux/Mac:
./configure
makeA compiled binary for MS Windows is already supplied. However, if you need to modify something or want to compile it yourself, you will need MS Visual Studio (I used MS Visual Studio 10, freely available from Microsoft). To compile, open a command shell and type:
c:\> nmake -f Makefile.win clean
c:\> nmake -f Makefile.win
