As Unix users, we know there are so much paths in our system. From / to /home, etc, etc. And you knew these paths are assigned to particular files and folders. For example, /home is home users directories while /opt is the path for packages installed. But, how did it went like that? And why? Rob Landley, who maintain Linux Firmware and an ex-maintainer of BusyBox, is trying to tell us the story behind these paths.

Working on Linux environment is much easier and –a lot faster– when you know how to use command line. Even knowing basic operation of command line is more than enough if you know the combinations. One of powerful commands in Linux is find. With this four character you find almost anything, from file located inside a directory to specific category of files or even rename files with particular condition. All can be done with find–and its combination of course.
