New tmux session which executes a script on startup

Question

On startup, I want to have a new tmux session created which inside of that session changes directory and executes a bash script. How do I do this?

Cheers,

Tom

Answer 1

Create the following script, but adjust it to your needs:

#!/bin/bash
Create a new session named "newsess" and run a command inside the session
tmux new-session -d -s newsess
tmux send-keys -t newsess "./path/to/myscript" Enter
Attach to session named "newsess"
tmux attach -t newsess

• newsess is the name of the session
• ./path/to/myscript is the full path of the script you want to run inside tmux.

Use any of the methods described here to run the above script on startup.
