External Tool (Labs) on Mac - how to

HansDieter_Zuch · November 25, 2024, 11:51am

Hi all!

I am new to the Mac version of Knime.
I am not able to run the external tool. On PC it was not a problem.
My current status is that I can open an app with the command line open -a program name.app
However I cannot pass an argument to open an %input% file.
I have setup an “exchange.txt” into the Documents folder, but Knime is not writing there. I can’t get any file passed to the external tool.
Help is appreciated.

thx

Hello @HansDieter_Zuch,

I believe you may need to use the exact naming of %inFile% or %outFile% for the placeholders in your command line as it says in the node instructions:

Hope this helps,
