NAME

kill.d - snoop process signals as they occur. Uses DTrace.

SYNOPSIS

kill.d

DESCRIPTION

kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal number and result.

This program can be used to determine which process is sending signals to which other process.

Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

Default output, print process signals as they are sent.: # kill.d

FIELDS

FROM: source PID
COMMAND: source command name
TO: destination PID
SIG: destination signal ("9" for a kill -9)
RESULT: result of signal (-1 is for failure)

DOCUMENTATION

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.

EXIT

kill.d will run forever until Ctrl-C is hit.
