[dtrace-discuss] Using regex matching in predicates

[Vasanth Bhat]

Hi,

      Is there way to regex based comparision in Predicates.
    For example,  if I want to  look for  only those processes which 
open the file    "myapp*.conf.*", how would  this be done in predicate?

syscall::open:entry
/(arg0 != NULL)&&   (copyinstr(arg0) == "myapp*.conf.*"/
{
   printf("File %s, opened by process %s[%d]\n",copyinstr(arg0), execname, pid);
}

I guess the above code will not work?   What is the correct way to do this.

I would like to avoid using system() to run another shell script or d-script.

Thanks
Vasanth
