in reply to manage file in parallel

Hi

In this scenario, I would suggest you to use pipe. Pseudo code :- 

run has to read the named pipe whether any user name there or not.
If user is there
   Give prefrences to the user
   write the second user name in the pipe, so that
   next time when run reads the pipe this will get the new     
   username
If no user
   run has to write the username in named pipe.

    First thanks for your fast reply. do you mean i need to use the $| =1 ? what if in the minute a user will open the file to write his name another user will try to write his name in the same , the action will fail, isn't ?
