      I am looking for a document explains all the signals' meaning and trigger.

      The signals special to Perl, like __WARN__ and __DIE__, are documented in %SIG, the other signals are generally POSIX signals, which you can read about for example in signal(7) like here and here, or in Signal (IPC). Note that a lot of signals may be OS-specific. If you could tell us what you want to use them for (and on which platforms), perhaps we can give more specific advice.

        Oh! Thank you so much! Learned something really new today, those SIGs are actually POSIX and IPC stuff, no wonder I don't get much useful results on my search before. I am working on Windows tho.
