Interactive test for Ctrl+C and Ctrl+D in cmux terminal.
|
|
|
|
This script tests that control signals are properly handled.
|
|
Run this script inside the cmux terminal.
|
|
|
|
Tests:
|
|
1. Ctrl+C (SIGINT) - Should interrupt a running process
|
|
2. Ctrl+D (EOF) - Should signal end-of-file on stdin
|
|
|
|
Usage:
