This example shows how to use the external tool to increment all numbers in a column by 1. Make sure to adjust the paths in the settings of the external tool node (The script is created inside the workflow in a folder called "test").
Executing this workflow will:
1) Create a textfile in.txt with the contents of the table creator
2) Call a script script.sh which will increment its contents and write that to a new file called out.txt
3) Now the output of out.txt is available at the output port of the External Tool node.
