ExecuteStreamCommand to call 'unzip -l'

[#1]

Is it possible to use ExecuteStreamCommand process to run 'unzip -l xxxx.zip' on an zip file that is in the flow and then return the zip's file list into an attribute?  If so how do I set it up not using a shell script?

@code_mnkey, what you are trying to achieve is not directly doable with a single command. You would need to build a script which will execute your unzip command, list all the files which have been extracted, create an attribute in your new flowfile and send it down the stream into further processing. The language in which you build the script is mostly up to you, as long as you have everything installed on your NiFi machine.

Another way, besides ExecuteStreamCommand, is to use ExecuteScript and build a script integrated with the NiFi's logic. A very good example of how you can achieve most of your expected actions can be found here: https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-1/ta-p/248922

Make sure that you read all three parts to fully understand how to generate flowfile, compose attributes and send newly generated flowfiles down the stream.
