minix_visualizer's Introduction

Minix Visualizer

This is a simple command line visualizer of log files generated with the Hacking the Minix Kernel project.

Usage

python minix_visualizer.py <filename> [-v|-vv]

Example:

python minix_visualizer.py log_e9.log -v

By default, it shows a summary of the keys pressed. If the -v option is used, it also shows every MAKEKBD event. If the -vv option is used, it shows every event.

Output

Example of non-verbose output:

--- Keys pressed: ---

###usuario
echo John Doe
exit
root
halt
