Set the terminal window title to display the current host name

When using a terminal in a Mac, especially when connecting to multiple SSH services, it is easier to identify the currently connected host in the Window tab.

Just started with a bit of a problem, if SSH to Server-a, the terminal title will become more server-a, but exit back to the machine, the title still shows Server-a, search for a bit just to solve the problem.

The conditions for achieving this result are as follows:

A. Setting environment variables

Export prompt_command= ' Echo-ne "\033]0;${user}@${hostname}: ${pwd}\007" '

Add this line of statement to ~/.bash_profile

B. The terminal type should be xterm

Can be found in the settings, advanced inside.
