File System Hierarchy Standard (FHS)
a document that specifies the layout ofdirectories on a Linux system. Was devised to provide a common layout to simplifiy distro independent software development. Specifies the directory tree.
What does FSHS specify?
The Filesystem Hierarchy Standard specifies the following directory tree
/ , /boot, /dev, /etc, /lib, /mnt, /opt, /sbin, tmp, /usr, /var.
the root directory
denoted by " / " contains the files you need to boot the system. Only filesystem auto mounted in single user mode. consists of sub directories and the kernel executable image file.
How do you make a file system accessible?
Mount the file system. a file system must be mounted to a directory to be accessible.
The linux system does not store the file name in the nod, so file can have multiple names. This means the file has more than one link. File is accessible by anyone.
