  • /usr/bin,/usr/sbin,/usr/lib, where the shared library (dynamic link library) is stored in the/usr/lib directory.
  • /etc. the standard UNIX system configuration file stores directories, such as user password file/etc/passwd. This directory is actually a link to/private/etc.
  • /dev Device File Store directory, how to represent the/dev/disk0 of the hard disk.
