5. Status Variables *terminal-emulator-status*
Terminal buffers maintain some information about the terminal in buffer-local
variables:
- *b:term_title* The settable title of the terminal, typically displayed in
the window title or tab title of a graphical terminal emulator. Programs
running in the terminal can set this title via an escape sequence.
- *b:terminal_job_id* The nvim job ID of the job running in the terminal. See
|job-control| for more information.
- *b:terminal_job_pid* The PID of the top-level process running in the
terminal.
These variables will have a value by the time the TermOpen autocmd runs, and
will continue to have a value for the lifetime of the terminal buffer, making
them suitable for use in 'statusline'. For example, to show the terminal title
as the status line:
>
:autocmd TermOpen * setlocal statusline=%{b:term_title}
