Clearer tab title for ssh-configurations immediately running a command like tmux, currently it is just OpenSSH SSH client without hostname

[fjellvannet]

Description of the new feature/enhancement

It is possible to specify ssh-configurations, so instead of putting e.g. wsl.exe -d ubuntu, one can write ssh user@hostname into the command line field of the configuration to immediately ssh onto a host when a new tab is opened. When the configuration is like that, the tab title looks like this including the hostname (all good):

However, when I change the configuration to ssh user@hostname -t tmux a to immediately attach to a tmux session, I see the following:

This is not very handy, as I can't see which host I am connected to, only that it is through ssh. The behaviour is actually exactly the same if I open a powershell tab, and then run ssh user@hostname -t tmux a, also here the title now is just OpenSSH SSH client. If I only run ssh user@hostname in powershell, I see the hostname in the windowtitle as indicated in the first image.

Proposed technical implementation details (optional)

1. A simple solution to this would be the ability to manually override the tab title for a configuration. Just always show some fixed text.

2. The nicer solution would be to actually fix the behaviour of how the hostname is displayed when the ssh-command is run with the -t option in General, so that it also works when I manually run the command in powershell.

But as option 2 most likely is more complicated / probably requires changes in the openssh client or the powershell configuration, solution 1 would be sufficient for now.

The indicated closed issues are similar, but not the same. The problems indicated there have been fixed.

This issue however has not been fixed yet.

I found a setting for profiles that is "suppressApplicationTitle", which gives the behaviour I suggested as solution 1. The profile's name will then just be displayed instead of the applicationTitle the process itself returns.

However, solution 2 would be better if it is possible to get it to work. It is very weird that the windows openssh client only displays a default applicationTitle once the -t option is used.

A potential option 3 would be to configure tmux to properly propagate the title from its hosted application up to the terminal emulator! It looks like your shell is configured to emit a title, and that tmux is dropping it. That would also make sure that the title updates when you switch panes inside tmux.

That's genious! What a simple fix. Immediately solved my problem - better than that even. Didn't think far enough myself to realise this was the problem.

I now just added set -g set-titles on to my tmux conf.

Also, I must say that I am impressed by your insanely fast response time! Thank you so much

see my last comment, that's the solution.
