Description Leonid Evdokimov 2008-02-03 06:52:56 UTC

bashrc uses <esc>_ as «start» of screen title, <esc>k should be used according to man screen/TITLES

BUG #75670 also mentions that screen $TERM should be checked as "screen*", not as "screen"

Reproducible: Always

Steps to Reproduce:
1. start screen
2. C-a "
3. Look at title :)

Actual Results:  
title of the window is "bash"

Expected Results:  
title should look like user@host:~

bashrc patch

Is there anything wrong with this trivial patch?

i dont particularly care ... if the screen maintainer says it's ok, then it may be committed

I'm totally against dynamically changing the screen window title. The screen window title is actually a name for a window and not something where auxiliary information can be shown. It reflects how the user names his/her screen windows and it can be used to jump to windows by name. Hence it should be constant and never changed by an application.

The hardstatus, which is what we currently set, is the correct way for such information. For xterm we also set the hardstatus and xterm propagates it up as the X window title.

Comment 4 Leonid Evdokimov 2009-01-11 15:06:13 UTC

I agree, hardstatus may be better place than window name.
Maybe, the bug should be resolved as `invalid'.

i think that's what Sven was going for :)

Comment 6 Dennis Schridde 2011-01-01 10:36:26 UTC

This should probably be documented, or even configurable via useflag.

looks like this was done via bug 359389
