Run in the interactive

I need your help! I try to run in the ‘interactive mode’ as shown below
build$ ./iridiumMain
then it runs and shows the geometry and at the end of the terminal it expects
Idle> in order to run using the command
Idle> /control/execute
However, it it says Changing export format to “jpg” as put here below
Changing export format to “jpg”
Would you please indicate to me where I made the mistake?
Thank you
