I found a great list of signals in Linux.


Signal name Number Default action Description

SIGINT 2 Term This signal is sent by C on the terminal
SIGTRAP 5 Core Trace/breakpoint trap

SIGPIPE 13 Term Write on a pipe with no one to read it
SIGALRM 14 Term Expiry of alarm clock timer
SIGTERM 15 Term Polite “please terminate” signal
