Shell orientation

Where you are, who you are

The prompt is your foothold. Know who you are and where you stand before you touch anything.

pwd — print working directory
whoami — current user
$ — user prompt · # = root
~ — home directory
/ — filesystem root
. — here
.. — parent
Tab — autocomplete

// terminal

GNU bash, lab shell. Type help

Who am I? (whoami)
Where am I? (pwd)

// lab

Run whoami and pwd; write both in lab-notes.md.
Run echo $SHELL and note which shell you use.
Run uname -a; note OS/kernel line.

// check yourself

Prompt ends with # instead of $. What does that usually mean?
