NiFi ExecuteCommandStream with sed

Question

I'm trying to run a sed command through a ExecuteCommandStream but I get the error pasted below. The ExecuteCommandStream has the input from a EvaluateXPath processor. How do I give the flowfile argument? I'm getting this error:

ExecuteStreamCommand[id=9c7cfd48-0171-1000-1a59-064ce951124a] Transferring flow file StandardFlowFileRecord[uuid=e448ca5a-8dc8-4754-a0d4-549db92d1f79,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1587501858734-9104, container=default, section=912], offset=375435, length=-1],offset=0,name=DL_prelchim1971_20190302_142639_20190302_145642.xml,size=0] to nonzero status. Executable command sed ended in an error: Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file].

You have to provide full path of your script in "Command Path" Attribute.

All the flowfile arguments can be passed in "Command Arguments" Property.

In below example, I am considering that I have a shell script created under /tmp directory with the name yourscript.sh

This script should have all the logics inside to handle receiving arguments and other logics.

Script Content (/tmp/yourscript.sh)

#!/bin/bash

echo $1

Expected Output: Just print the name of the FlowFile inside the flow file content.
