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.
