NAME

signal − list of available signals

DESCRIPTION

Linux supports the signals listed below. Several signal numbers are architecture dependent. First the signals described in POSIX.1.

Next various other signals.

(Here − denotes that a signal is absent; there where three values are given, the first one is usually valid for alpha and sparc, the middle one for i386 and ppc, the last one for mips. Signal 29 is SIGINFO / SIGPWR on an alpha but SIGLOST on a sparc.)

The letters in the "Action" column have the following meanings:

A

Default action is to terminate the process.

B

Default action is to ignore the signal.

C

Default action is to dump core.

D

Default action is to stop the process.

E

Signal cannot be caught.

F

Signal cannot be ignored.

G

Not a POSIX.1 conformant signal.

CONFORMING TO

POSIX.1

BUGS

SIGIO and SIGLOST have the same value. The latter is commented out in the kernel source, but the build process of some software still thinks that signal 29 is SIGLOST.
