Determine if only one instance is running
Why did you prefer to use files over semaphores here? Is it just that the deletion of files is easier than it is for semaphores, or are there other reasons?
FWIW I am planning to phase out the use of .pid files by implementing a multiplex handler that allows for registration of unique instances (possibly using a semaphore like mechanism). - If the process dies, the unique instance will become unregistered (hopefully by the kernel).

Thanks for the cleanup work you've been doing. I haven't had time to do my round of greetings in months, but be aware that your activity is observed and appreciated. :) --Michael Mol 12:19, 8 April 2011 (UTC)
I noted that you removed the incorrect templates to Factor and Golfscript here. I had marked them for not showing their output when it was mentioned in the task description and given by many other examples on the page. You didn't supply the missing output however and I was wondering what your interpretation was?

I notice that you reverted my edit "unset" to "set --". As far as I know unset is compatible across all Bourne compatible shells, but set -- is not. (It is certainly an undocumented feature not mentioned in some of the Unix books that I have). Is there a particular problem with unset? Markhobley 15:55, 12 September 2011 (UTC)
