I have been a tmux user for long time now. Oddly enough I haven’t tinkered with my tmux config from when I first crafted it. Probably just updated once when a tmux upgrade broke the config.
Recently I wanted to merge windows of one session into another.
I wrote a small script to achieve this:
# merge_session.sh
#!/bin/bash
source_session_id=$1
dest_session_id=$2
dest_session_window_count="$(tmux list-windows -t "$dest_session_id" -F "#{window_index}" | tail -n1)"
for i in $(tmux list-windows -t $source_session_id -F "#{window_index}");
do
dest_session_window_count=$(($dest_session_window_count + 1))
echo $dest_session_window_count
tmux move-window -s $source_session_id:$i -t $dest_session_id:$dest_session_window_count
doneThe input to this script is session id of the windows that you want to merge from and session id to merge to.
