filebyproc.d - snoop opens by process name. Uses DTrace.
filebyproc.d is a DTrace OneLiner to print file pathnames as they are
opened, including the name of the process calling the open. A line will
be printed regardless of whether the open is actually successful or not.
This is useful to learn which files applications are attempting to open,
such as config files, database files, log files, etc.
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
This prints new process name and pathnames until Ctrl-C is hit.

See the DTraceToolkit for further documentation under the Docs directory.

descriptions explaining the output.
filebyproc.d will run forever until Ctrl-C is hit.
