There is one default server process per user which puts its socket in
/tmp/tmux-UID. It is created the first time tmux is run and subsequent
invocations will connect to the same server. The server holds multiple
sessions.

Syntax is: tmux [-v] [-S path] [-s session] command [flags]

    -v Create logfiles, verbosity increases with more -v
    -S Set different server socket path
    -s Specify session name for command, if appropriate.

If a session name is not given, the current session is assumed if a command
is run from inside tmux and the TMUX environment variable is available,
otherwise if only one exists, it is used or if multiple exist, an error is
generated.
