Show HN: Sigwire – a live TUI switchboard for every signal on your Linux box
Sigwire is a new Linux tool that provides a live, terminal-based interface for monitoring system signals across all processes. By hooking into kernel tracepoints, it allows developers to observe signal generation and delivery without modifying or instrumenting individual applications.
tail -f for signals. Every signal any process on the box raises — who sent it, who it hit, which signal, how it was raised ( kill(2) , the kernel, a POSIX timer), whether the target caught it and how long its handler ran, whether it tore a blocked syscall out with EINTR — decoded off the kernel's signal tracepoints and streamed live to your terminal. No strace -f on one pid, no ptrace , no cooperation from the processes involved.
