If I'm understanding what you are saying, you have a whole bunch of perl scripts, and you need to change one line (#!/usr/bin/perl??) to #!/usr/local/bin/perl on all of the perl files in a dir? If that is the case technically you could write a perl script to do it. It wouldn't take long, or much to hack one out. Is my understanding correct?

Yes, I am a criminal.
My crime is that of defyance.
