copying to clipboard doesn't work in a remote session (like a devcontainer)

[bretthoerner]

Description

For example: /share is great but it appears to only support copying directly to the clipboard. It'd be nice to print the actual URL so people can copy it from a terminal themselves, or even better it'd be nice to support copying out to the host automatically.

The wrapper helped me in a vscode devcontainer:

+#!/bin/bash
+# OSC 52 clipboard wrapper for devcontainers
+# Sends clipboard data to the host terminal via OSC 52 escape sequences
+# This works in VS Code terminal and most modern terminal emulators
+
+# Read from stdin and base64 encode
+data=$(cat | base64 | tr -d '\n')
+
+# Write directly to the controlling terminal, bypassing any TUI that might
+# be capturing stdout. This ensures the escape sequence reaches VS Code.

+else
