# Linux Fundamental Series - Episode 03

# *Are you Busy?* Spare a Minute !

### A quick read will help you learn the three most  *IMPORTANT* and *BASIC* commands in *LINUX*

COMMAND 1:

> hostname

The command *hostname* displays the name of the system you are logged in. It is always a good practice to check if you are logged on to the necessary host. 

COMMAND 2:

> whoami

The command *whoami* displays the id of the user logged in. It is a way to check if you are logged in with the right account before performing any operation.

COMMAND 3:

> pwd

The command pwd displays the information on the directory you are in.

These commands help us check on the basic information like the name of the system we are logged in, userid with which we are accessing the system and the working directory we are in.

Happy Learning!
