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.

This matches file creates from the creat() system call; not all file creation occurs in this way, sometimes it is through open() with a O_CREAT flag, this script will not monitor that activity.

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 verbose descriptions explaining the output.

EXIT

creatbyproc.d will run forever until Ctrl-C is hit.
