I use this:

DIM sShellOutput as String
SHELL "pgrep -f -U " & User.Name & " " & Application.Args[0] TO sShellOutput
  
   IF Split(Trim$(sShellOutput), "\n").Count > 1 THEN 
     
     'already running
     'take action here
   
   ENDIF  

This check for the user. If you want to check system
wide, do:

SHELL "pgrep -f " & Application.Args[0] TO sShellOutput

Bye,

Stefano
