Funny, I had to experiment a bit to see how it worked. This is surely a FAQ, because it's important. IMHO, the interpreter for a Unix program should be invisible, so that the program behaves like as a first-class process in every way. $ python foo1.py This one gets called 'python', as expected. $ head -1 foo2.py #!/usr/bin/env python $ ./foo2.py This one gets called 'python', too. I've been using this version because I read somewhere it was the recommended idiom -- but I will stop doing it now that I know it mangles the process name. $ head -1 foo3.py #!/usr/bin/python $ ./foo3.py This is the traditional shebang form used for shell and Perl scripts, and it names the process 'foo3.py' so you can killall(1) it nicely. > Or am I stuck with > registering the pid of each python process I create and then refer to > that list whenever I need to selectively stop one of them? If a program starts another one and needs to kill it, it /should/ remember its pid. You don't want programs which cannot live together on one machine without killing each other's children. But as I wrote above, you /do/ want to have meaningful information in top(1), ps(1) and so on. Having half a dozen processes named python (or java, or whatever) and wanting to kill one specific is not my idea of fun ... /Jorgen -- // Jorgen Grahn <grahn@ Ph'nglui mglw'nafh Cthulhu \X/ snipabacken.dyndns.org> R'lyeh wgah'nagl fhtagn! -- http://mail.python.org/mailman/listinfo/python-list
