Signals in Linux

[ Thanks to linuxaria for this link. ]

“A signal is an event sent by the kernel to a running
program.

“The signals can arrive at any time and software can choose what
to do when it arrives: it can decide to ignore it or may decide to
execute a signal handler and continue with what he did.

“There are 31 different signals, and you can see them with:

” kill -l”
