How do I get the current user’s username in Bash?

In Bash, you can get the current user’s username using the whoami command or by accessing the $USER environment variable.

Method 1: Using whoami command

username=$(whoami)
echo $username

Method 2: Using $USER variable

echo $USER

Both methods will return the username of the currently logged-in user. The whoami command is often more reliable, especially if the script is run by a different user.
