Fixing tmux Socket Issues

Acerca de

When system cleanup scripts or manual deletions remove the tmux socket from temporary directories, users often face frustrating connection errors even while their sessions are still running. This skill provides a specialized diagnostic and recovery workflow to recreate the necessary socket infrastructure and signal the tmux server to re-establish its filesystem presence. By following these steps, you can restore full functionality to commands like list-sessions and automated plugins like tmux-resurrect without losing any work or killing existing terminal processes.
