How can I get the current user's username in Bash?

Question

I am writing a program in Bash that needs to get the user\'s username.

I have heard of a thing called whoami, but I have no idea what it does or how to use it.

Answer 1

On the command line, enter

whoami

or

echo "$USER"

To save these values to a variable, do

myvariable=$(whoami)

or

myvariable=$USER

Of course, you don't need to make a variable since that is what the $USER variable is for.
