    # Piece-by-Piece Explanation:
    # the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
    # iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
    # the $PROMPT_COMMAND environment variable is executed every time a command is run
    # see: ss64.com/bash/syntax-prompt.html
    # we want to update the iTerm tab title to reflect the current directory (not full path, which is too long)
