C.10 Frame Titles
Each Emacs frame always has a title, which appears in window
decorations and icons as the name of the frame. The default title is
of the form ‘ invocation-name@machine
’ (if there is
only one frame) or shows the selected window’s buffer name (if there
is more than one frame).
You can specify a non-default title for the initial Emacs frame with a command line option:
‘ -T title
’ ¶‘ --title=title
’
Specify title as the title for the initial Emacs frame.
The ‘ --name
’ option (see X Resources) also specifies the title
for the initial Emacs frame.
