Signals are used to generate interruptions for the processes like abort, wait, interrupt, kill, delete, suspend etc.
In these 64 signals, first 32 signals are used to generate the interruptions.
use the bellow command to view the list of signals, enter in terminal

kill -l


and open manual page for each signal description
ex: man abort
man kill
