About the dtrace Command

The dtrace command provides a generic interface to all the essential services that are provided by the DTrace facility.

The dtrace command includes options to do the following:

List the set of probes and providers published by DTrace.
Enable probes directly by using any of the probe description specifiers (provider, module, function, name).
Run the D compiler and compile one or more D program files or programs written directly on the command line.
Generate program stability reports.
Change DTrace tracing and buffering behavior and enable extra D compiler features.

You can also use the dtrace command to create D scripts by using the command in a #! declaration to create an interpreter file. Finally, you can use the -e option to dtrace to compile D programs and find their properties without enabling any tracing.
