FAQPage Schema

How do I run a parallel Claude Code session in tmux without losing my current conversation history?▼

You can fork a Claude Code session into a parallel tmux window to run independent conversations while preserving the original session's history and continuing ongoing work without interruption.

What do I need to set up before forking a Claude Code session into a new tmux window?▼

Forking a Claude Code session requires tmux and the cld-fork script installed. Optional session-state.sh and session-comm.sh utilities add monitoring and completion reporting capabilities.

Can I get a notification when a forked tmux session finishes its task?▼

Yes, the fork function supports an optional watch mode that monitors the parallel session and provides completion reports, utilizing session-state.sh and session-comm.sh utilities for notifications.

What is the best way to handle parallel conversations when I need to keep my main Claude Code session uninterrupted?▼

Forking the current session into a separate tmux window is the best approach, as it creates an independent parallel conversation while leaving the original session completely unchanged and active.

Does forking a session affect the original tmux window's ongoing work?▼

No, forking a session preserves the original session entirely. The new tmux window runs as an independent parallel conversation, allowing you to continue work in both windows separately.
