NAME
creatbyproc.d - snoop creat()s by process name. Uses DTrace. SYNOPSIS
creatbyproc.d DESCRIPTION
creatbyproc.d is a DTrace OneLiner to print file creations as it occurs, including the name of the process calling the open.

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 process names and new pathnames until Ctrl-C is hit. # creatbyproc.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 The first is the name of the process, the second is the file pathname. 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
