Dear Monks

when I think more and more about the problem challenge I'm dealing with, the solution doesn't seem to get any closer.....

The program in question normally only reads stuff, so multiple instances are OK. However, when the options, lets say -w is used, some writing will be involved too. Meaning that there can only be 1 instance running with the -w options.

It seems that LockFile::Simple is a good solution, but if possible I would like to have a solution that doesn't create any files!
I tried Unix::PID as well but it seems there is now way to tell what the commanline agruments are of the instance already running.

Any other suggestions how to determine what the commandline parameters are from an other instance ?

Thnx a lot
LuCa
