t is a small wrapper around tmux. Its usage is as follows.

• t list: List available tmux sessions (equiv to tmux list-sessions).
• t new NAME: Create a new session with the specified name (equiv to tmux new-session -s NAME).
• t NAME: Attach to the named session (equiv to tmux attach -t NAME); t attach NAME also works.
• t (no arguments): Runs tmux attach || tmux which will either attach to the last session or start a new tmux instance.

t_func.sh

# add this to your ~/.bashrc or whatever
function t() {
  if [ -n "$1" ]; then
    if [ "$1" = "list" ]; then
      tmux list-sessions
    elif [ "$1" = "new" ]; then
      if [ -n "$2" ]; then
        tmux new-session -s $2
      else
        tmux
      fi
    elif [ "$1" = "attach" ]; then
      tmux attach -t $2
    else
      tmux attach -t $1
    fi
  else
    tmux attach || tmux
  fi
