| Exit Code | Description |
|---|---|
| 0 | Complete the flow, stop execution |
| 1 | Output 1 |
| 2 | Output 2 |
| Unknown | If the exit code is out of range of the defined outputs, then this will be treated as a failure |
Variables
In a flow Variables can be used, these will be basic string replacements, which will be done to the script code before creating the .bat file.
Variables can be used using {VariableName}, for example
# Replace {file.FullName} and {file.Orig.FullName} with actual values
WorkingFile="{file.FullName}"
OriginalFile="{file.Orig.FullName}"
# Example commands using the variables
echo "Working on file: $WorkingFile"
echo "Original file location: $OriginalFile"
# Set the exit code to
exit 1
