in thread Finding what args were passed to the perl interpretter ?

How would a perl script attach an strace to itself in such a way that it can see its own invocation? If I simply do system "strace -p $$" then it's too late (the execve occurred in the past!)

    Well, the idea would be to attach strace to whatever is calling perl... Why would you want to do it from within the script itself?

      See my previous post: I was wanting the script to figure out if it was invoked using "-d:NYTProf". I like JavaFan's approach of checking if Devel::NYTProf->can("import") -- though obviously that's not ideal.

      I was sort of hoping to answer the more general problem: some form of auto-populated $PERL5OPTS that I can use in much the same way as ${MAKE} in recursive makefiles. But the specific answer is good for now
