how to get rid of ttys000 in terminal

From Terminal's help:

Change the title shown in the Terminal window

You can change the text in the title bar of a Terminal window to display a variety of information about the window’s configuration.

1. Choose Terminal > Preferences, and then click Settings.
2. Click Window.
3. Select a setting to modify from the Settings list, located on the left side of the Settings pane.
4. In the Title section, enter the name you want to appear in the title bar of the Terminal window.
5. Select the items you want to appear in the title bar of the Terminal window:

   Active process name:	The currently running process.
   Shell command name:	The shell being used in the window.
   Settings name:	The settings being used to configure the window.
   TTY name:	The current name of the terminal. The name is equivalent to the result of the tty command in UNIX.
   Dimensions:	The number of columns and rows in the window.

Sbermans answer is good, however your issue may have something to do with how you close terminal in the first place. If you use Command+q and then open with Command +space it will try to restore your sessions.
