Unit 9: The File System

portrayed as being above all other. It is the highest place you can go to. Beneath it are almost Notes
always only directories:
~$ cd /
~$ ls -F
bin/ home/ opt/ srv/ var/
boot/ lib/ proc/ sys/
dev/ media/ root/ tmp/
etc/ mnt/ sbin/ usr/
The ls -F commands displays the content of the root location. However, it appends an additional
character to special files. For instance, it appends a “/” to directories, an “@” to symbolic links
and a “*” to executable files. The benefit is that you can easily see what type of files you have.
A popular method of representing the file system is through a tree.

Example: An example would be for the top level:

/
+- bin/
+- boot/
+- dev/
+- etc/
+- home/
+- lib/
+- media/
+- mnt/
+- opt/
+- proc/
+- root/
+- sbin/
+- srv/
+- sys/
+- tmp/
+- usr/
`- var/
This is to note that he more you descend, the larger the tree becomes and it will soon be too
difficult to put it on a single view. Still, the tree format is a good method of presenting the file
system as it shows exactly how the file system looks like.
