Starting tmux with a default set of tabs

You can easily start tmux with a predefined set of tabs open, with names and current working directory set... I use this for example:

  • in iTerm2 -> Profiles -> your profile -> Send text at start -> /bin/bash ~/bin/start-tmux
  • ~/bin/start-tmux example shown below
#!/bin/bash

[ ! -x "$(command -v tmux)" ] && echo "tmux not installed" && exit 1
[ -n "$TMUX" ] && echo "already in tmux" && exit 1

if ! tmux has-session -t main 2>/dev/null; then
  tmux new-session -d -s main -n first-window
  tmux new-window -n second-window -c ~/
  tmux new-window -n third-window -c ~/
fi
tmux attach-session -t main
