What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

A small C wrapper program (reattach-to-user-namespace) plus documentation that fixes broken Mac OS X pasteboard (pbcopy/pbpaste) access inside tmux and unpatched screen sessions. The functionality was merged into tmux 2.6, so the tool is mainly needed for older tmux versions.

Use cases

  • fix pbcopy and pbpaste not working inside tmux on macOS
  • enable clipboard access in screen sessions on Mac OS X
  • reattach processes to the user's login namespace under tmux
  • configure tmux default-command to preserve macOS clipboard
  • make other macOS GUI-connected programs work inside terminal multiplexers

When to choose

  • you run an older tmux (< 2.6) or unpatched screen on macOS and need working clipboard access
  • you need a lightweight wrapper instead of patching tmux or screen
  • other programs lose access to the GUI session when launched from tmux

When to avoid

  • you use tmux 2.6 or newer, which has this functionality built in
  • you are not on macOS
  • you need an actively developed tool with ongoing updates
