One of the main reasons I use tmux is to be able to organize the various
development servers and tools I have to run for a given project. They can be
spread across several windows in the same session. Or for ease of access, they
can all be split across panes in a single window.
In that latter case, I recently ran into an issue where the server output in each pane looked similar enough that I couldn't tell which was which. What I need is titles for each pane that tell me what is running and where.
tmux has pretty solid support for just this out-of-the-box with
pane-border-status.
Hit <prefix>: to issue the following command to tmux:
:set pane-border-status top
Or issue the command from one of your pane's terminal prompts:
$ tmux set pane-border-status top
Either way, it will replace the top border line with text telling you the pane number, the directory, and the last run command in that pane. This is just the context I need to differentiate each.
This will only set it for the current window.
If you want to turn it back off:
:set pane-border-status off
