woof.d - Bark for new processes. Needs /dev/audio. Uses DTrace. woof.d & This is an audio alert daemon for process creation. It is a virtual dog which barks when it sees new processes. If many processes are being created quickly, it will bark a lot (and become a nuisance - not just the noise, but also from consuming too much CPU). This exists in the DTraceToolkit more for entertainment than practicality. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the proc provider, /usr/bin/audioplay, and bark.au.

Run the dog, # woof.d &

Hear the dog, $ find /etc -type f -exec grep localhost {} +

Drive the dog crazy, $ find /etc -type f -exec grep localhost {} \\;

Beware of the dog!

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output. woof.d will exit on Ctrl-C. Brendan Gregg [Sydney, Australia] sdtaudiocontrol(1), dtrace(1M)
