kitchen.sh, pan.sh, spoon.sh all launch the spoon.sh GUI

Hello! I'm an overall new user. I've been using kettle from 6.1 and all was working well. I upgraded to 7 because I hit a heap error, and though the upgrade would fix it, but turned out that experience is the best teacher. Now, on the 6.x version I was running a crontab which executed a job every night. Worked just fine.

The version of Kettle (7.0.0.0-25) that I'm using is the latest I could find. I'm pretty sure I'm doing something wrong, and here are my attempts:
I run kettle in debian linux.

at the command line:
./spoon.sh # results in the Kettle GUI being launched
./pan.sh # results in the Kettle GUI being launched
./kitchen.sh # results in the Kettle GUI being launched

rebooted the machine
tried this from my previous crontab:
./kitchen.sh -rep PentahoRepo -user standard -pass user1234 -dir PQRS2016 -job Measure1 # results in the Kettle GUI being launched

tried this instead:
./pan.sh -rep PentahoRepo -user standard -pass user1234 -dir PQRS2016 -job Measure1 # results in the Kettle GUI being launched

tried
./runSamples.sh #loads the GUI for each sample - waits for you to close the GUI, launches it successively a few times. Gets old.

tried
./kitchen.sh -rep=PentahoRepo -user=standard -pass=user1234 -listdir=Y # results in the Kettle GUI being launched

and now I'm here asking - what in the world am I doing wrong? Seems like these all should be doing different things, yet, no matter what I type, I get the same output.

Also, doesn't matter if I've had the Kettle GUI running while attempting these commands or not.
Hoping someone else ran into this and knows?

thanks,
Jack
