23$BUILTIN trap-
24$FUNCTION trap_builtin-
25$SHORT_DOC trap [-lp] [[arg] signal_spec ...]-
26Trap signals and other events.-
27-
28Defines and activates handlers to be run when the shell receives signals-
29or other conditions.-
30-
31ARG is a command to be read and executed when the shell receives the-
32signal(s) SIGNAL_SPEC. If ARG is absent (and a single SIGNAL_SPEC-
33is supplied) or `-', each specified signal is reset to its original-
34value. If ARG is the null string each SIGNAL_SPEC is ignored by the-
35shell and by the commands it invokes.-
36-
37If a SIGNAL_SPEC is EXIT (0) ARG is executed on exit from the shell. If-
38a SIGNAL_SPEC is DEBUG, ARG is executed before every simple command. If-
39a SIGNAL_SPEC is RETURN, ARG is executed each time a shell function or a-
40script run by the . or source builtins finishes executing. A SIGNAL_SPEC-
41of ERR means to execute ARG each time a command's failure would cause the-
42shell to exit when the -e option is enabled.-
43-
44If no arguments are supplied, trap prints the list of commands associated-
45with each signal.-
46-
47Options:-
48 -l print a list of signal names and their corresponding numbers-
49 -p display the trap commands associated with each SIGNAL_SPEC-
50-
51Each SIGNAL_SPEC is either a signal name in <signal.h> or a signal number.-
52Signal names are case insensitive and the SIG prefix is optional. A-
53signal may be sent to the shell with "kill -signal $$".-
54-
55Exit Status:-
56Returns success unless a SIGSPEC is invalid or an invalid option is given.-
