I would like to use figlet on the very first window of the tmux session that I have created using the following script: #!/bin/bash # log the date time in a log file date >> ~/logFiles/session.log # start a session called TWIN /usr/bin/tmux new-session -d -s TWIN # stay on even when the script crashes /usr/bin/tmux set-option set-remain-on-exit-on # Start the python script /usr/bin/tmux new-window -d -n 'bucket' -t TWIN:1 'sleep 20;                                              sudo /home/pi/bin/bucket.py' # Start checker script in the folder /usr/bin/tmux new-window -d -n 'checker' -t TWIN:2 'cd /home/pi/incoming;                                                      figlet Incoming;                                               /home/pi/incoming/checker' # Start the Bootstraploader script/usr/bin/tmux new-window -d -n 'bsl' -t TWIN:3 'cd /home/pi/bsl;                                          figlet BootStrapLoader;                                               /home/pi/bin/bsl'exit 0The above script generates the following Windows:0:sh | 1: bucket | 2: checker| 3: bslthe figlet letters work well in the window:2 and window:3 how ever I want to add a figlet on the 0:shI tried adding the following line:/usr/bin/tmux new-window -d -n 'welcome' -t TWIN:0 'figlet hello'in the above mentioned script but the output was the following:  ./createSession   unknown option: set-remain-on-exit-on  create window failed: index in use: 0I also tried the following: /usr/bin/tmux new-session -d -s TWIN 'figlet hello'but the output is : can't establish current sessionI would somehow like to use 0:sh which is created due to the creating new-session command.Is there a way I can use this? since everytime I log into the session using tmux a I get to see a blank session which isn't so coolNote:This is what figlet Incoming would look like (for those who do not use it) ___                           _             |_ _|_ __   ___ ___  _ __ ___ (_)_ __   __ _  | || '_ \ / __/ _ \| '_ ` _ \| | '_ \ / _` | | || | | | (_| (_) | | | | | | | | | | (_| ||___|_| |_|\___\___/|_| |_| |_|_|_| |_|\__, |                                       |___/
