[NiFi] Decompress a rar file on a flowfile


Hi, I get a rar file from a SFTP server, have it in a flowfile

I'm trying to run unrar on the flowfile with an executeStreamCommand withtout persisting it with no luck, tried setting working directory to /tmp too, unrar is in path an executing:


Is there any way to do this or I have to dump the files to disk, decompress them there with this processor and get the files again?
