     / - the topmost ( / means where the file system is stored like C: in windows )
   /dev - all the devices are accessible as files
   /var - “variable” data such as mails, log files, databases
   /usr - almost all the packages installed
   /etc - configuration files
   /home - home directories for all the users
   /root - home directory of the privileged user root
/mnt - used to mount other directories/partitions.

# rm it is used to delete files
                                 &
# rm -r it is use to delete directorys recursively
          usage : $ rm -r /root/folder

# mkdir it is used to create directory (folder)

usage : $ mkdir /etc/folder

# touch it is used to create files
            usage : $ touch /root/temp
