filebyproc.d(1m)

NAME
filebyproc.d - snoop opens by process name. Uses DTrace.

SYNOPSIS
filebyproc.d

DESCRIPTION
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 command.

EXAMPLES

This prints new process name and pathnames until Ctrl-C is hit.
    # filebyproc.d

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

EXIT
filebyproc.d will run forever until Ctrl-C is hit.
