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

NAME
newproc.d - snoop new processes. Uses DTrace. SYNOPSIS
newproc.d DESCRIPTION
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. EXAMPLES
This prints new processes until Ctrl-C is hit. # newproc.d FIELDS
CPU The CPU that recieved the event ID A DTrace probe ID for the event FUNCTION:NAME The DTrace probe name for the event remaining fields These contains the argument listing for the new process DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver- bose descriptions explaining the output. EXIT
newproc.d will run forever until Ctrl-C is hit. AUTHOR
