One of the most handy commands to use in terminal for navigation in the terminal is the LS command. The LS command will list all files and folders in your present working directory. The syntax works something like this:
ls: displays contents in list view of folder
ls -l: displays contents in list view of folder
ls -a: displays all content of folder even hidden ones
There are other terminal commands to know when surfing the file system:
pwd: displays present working directory, think of it as a “you are here” in terminal
cd: change directory
With the above commands you can surf the terminal and learn a lot about your filesystem and do it safely.
