hier - Description of the file system hierarchy
A typical Linux system has, among others, the following directories:
/ This is the root directory. This is where the whole tree starts.
/bin This directory contains executable programs which are needed in single user mode and to bring the system up
or repair it.
/boot Contains static files for the boot loader. This directory only holds the files which are needed during the
boot process. The map installer and configuration files should go to /sbin and /etc.
/dev Special or device files, which refer to physical devices. See mknod(1).
/dos If both MS-DOS and Linux are run on one computer, this is a typical place to mount a DOS file system.
/etc Contains configuration files which are local to the machine. Some larger software packages, like X11, can

Nevertheless, programs should always look for these files in /etc and you may have links for these files to
