I'm not really clear with my question here, let me rephrase it :

I've setup a launch_workspace.sh to launch directly tmux with 5 different commands loaded. Here is my current content :

#!/bin/sh

tmux new-session -d -s scube -n 'vim' "vim"

tmux new-window -t scube:2 -n 'server' "$SHELL -c 'script/rails server'"
tmux new-window -t scube:3 -n 'yard' "$SHELL -c 'bundle exec yard server --gems'"
tmux new-window -t scube:4 -n 'spork' "$SHELL -c 'bundle exec guard'"
tmux new-window -t scube:5 -n 'autotest' "$SHELL -c 'bundle exec autotest'"
tmux new-window -t scube:5 -n 'shell' "$SHELL"

tmux select-window -t scube:1
tmux -2 attach-session -t scube

Problem is : my zsh ($SHELL beeing zsh) launches said commands, but when I Ctrl+C any of these, it closes the full zsh (hence my tmux window) and not just return to a proper zsh prompt.

Is there a way to have said behavior, to launch zsh with a command and return to a zsh prompt when the command fails ?

Cheers
