Set name of windows in tmux/byobu to hostnames of servers you're connected to

for i in $(tmux list-windows -F '#{window_index}'); do panenames=$(tmux list-panes -t $i -F '#{pane_title}' | sed -e 's/:.*$//' -e 's/^.*@//' | uniq); windowname=$(echo ${panenames} | sed -e 's/ /|/g'); tmux rename-window -t $i $windowname; done
*I run this with byobu as as a custom status bar entry that runs every 10 seconds by putting it in a script here: .byobu/bin/10_update_windows There's no output to stdout, so nothing is displayed on the status bar. *Presumes that #{pane_title} is set to the hostname or prompt containing the host name. In my case, it's in this format: $USER@$HOSTNAME:$PWD The sed commands may need to be modified if your pane_title is different. *If you want to strip out a common part of a hostname, add the following before '| uniq' -e 's/[COMMON PART]//' I use that to strip out the domain of the servers I connect to, leaving the subdomain.
Sample Output
(In window listing section of status bar)
0:capone.blah.com  1:hermes.blah.org|ihub.halb.org|web01.com* 2:charlie.unicorn.com- 3:alpha02.example.com
