General Structure#

In Linux, / represents the root of the entire directory structure. The structure is actually a tree like structure. Check this out:

The . represents the current directory, which in this case is / in the structure (the root.)

Micro Project#

1. Investigate (Google) the, "linux directory structure"
   1. What do your results tell you about /bin, /mnt, /tmp, and /home?
2. Install the tree utility: sudo apt install -y tree
3. Try this: cd / then tree -L 1
4. Now try this whilst still at /: tree -L 2
   1. Do you see the tree like structure now? Try tree (BIG list of results)
