filebyproc.d(1m) USER COMMANDS filebyproc.d(1m)NAMEfilebyproc.d - snoop opens by process name. Uses DTrace.
SYNOPSISfilebyproc.dDESCRIPTIONfilebyproc.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
command.
EXAMPLES

tory. The DTraceToolkit docs may include full worked examples with ver‐
bose descriptions explaining the output.
