The command ARG is to be read and executed when the shell receives
signal(s) SIGNAL_SPEC. If ARG is absent all specified signals are
reset to their original values. If ARG is the null string each
SIGNAL_SPEC is ignored by the shell and by the commands it invokes.
If SIGNAL_SPEC is EXIT (0) the command ARG is executed on exit from

If a SIGNAL_SPEC is EXIT (0) the command ARG is executed on exit from
the shell. If a SIGNAL_SPEC is DEBUG, ARG is executed after every
command. If ARG is `-p' then the trap commands associated with
each SIGNAL_SPEC are displayed. If no arguments are supplied or if
only `-p' is given, trap prints the list of commands associated with
each signal number. SIGNAL_SPEC is either a signal name in <signal.h>
each signal number. Each SIGNAL_SPEC is either a signal name in <signal.h>
or a signal number. `trap -l' prints a list of signal names and their
corresponding numbers. Note that a signal can be sent to the shell
with "kill -signal $$".
