[Gambas-user] How to avoid second instance?

[Alberto Torres]

Maybe using a lock file with the PID in it:

-Check if exists the lock file (say /tmp/yourapp.lock) and it has a 
number in it.
    -If so, check if the program with that PID is running (i.e. checking 
/proc/[pid], say pid is 12345, check if directory /proc/12345 exists)
       -If it is already running, exit
       -Else, replace the lock file writng Application.Id in it, and 
continue.
