TIL /usr doesn't stand for user, but User System Resources

POSTED ON:

TAGS:

/usr nowadays stands for User System Resources. This directory contains most commands and executables files, libraries and documentation. In the early days of Unix, it was the directory where the users' home directories were placed (your user home directory would have been /usr/anatoly which now is /home/anatoly), so originally it stood for User.
