A simple bash snippet to add to the end of your `.bashrc` to automatically enter tmux when you login through SSH

auto_tmux.sh

# Automatically start tmux for ssh connections

# This will _unconditionally_ run tmux. If tmux may not be available (e.g. you use the same .bashrc
# for multiple systems), you can wrap it in an if statement:
#
# if command -v tmux >/dev/null 2>&1; then
#     ...
# fi

# is interactive, is not in tmux, is in ssh
if [[ "$-" == *i* ]] && [[ -z "$TMUX" ]] && [[ -n "$SSH_TTY" ]]; then
    # Start a tmux session (`-A`: attach if it already exists)
    tmux new-session -A -s tmux-ssh
    # Uncomment the following line to automatically exit bash after exiting/detaching from tmux
    #exit
fi # MUST BE END OF FILE
