sess open

sess open <name> [--force]

Reopens a saved session. If a live tmux session with that name is already running, sess attaches to it instead of restoring — your saved snapshot is left untouched.

sess open backend-debug

Pass --force to kill the live session first and restore fresh from the saved snapshot instead of attaching to what's currently running.

sess open backend-debug --force

If the snapshot has any persisted environment variables, sess prints a one-line summary of what it restored. Selecting a session by state (running/saved/stale/broken) instead of by name directly? See switch and Session states.
