This Bash command retrieves the username of the currently logged-in user on a macOS system. Here's a breakdown of what it does:

• stat -f%Su /dev/console:

  • The stat command is used to display detailed information about files.
  • The -f option specifies a format string for how the output should appear.
  • %Su is the format specifier that extracts the username of the file's owner.
  • /dev/console refers to the terminal device representing the active console session (essentially, the user currently logged in on the system).

• currentUser=$(...):

  • This assigns the output of the stat command (the username) to the shell variable currentUser.

Summary:

The entire line of code gets the username of the currently active macOS user (the one logged into the system console) and stores it in a variable called currentUser.
