newproc.d(1m) USER COMMANDS newproc.d(1m)

newproc.d - snoop new processes. Uses DTrace.


newproc.d is a DTrace OneLiner to snoop new processes as they are run. The argument listing is printed.

This is useful to identify short lived processes that are usually difficult to spot using traditional tools.

Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.

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

# newproc.d

The CPU that recieved the event
A DTrace probe ID for the event
The DTrace probe name for the event
These contains the argument listing for the new process

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

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