Nifi ListFile not listing files starting with "."

chuck7 — Tue, 08 Feb 2022 21:24:06 GMT

We have file names that start with a dot (e.g. ".~tempfile.bin") that we are attempting to list with the ListFile processor. We've tried setting the File Filter to an empty string, as well as various RegEx's (e.g. ".*") and it will not list file names starting with a dot. As soon as we remove the starting dot from the file name, it lists the files. Any ideas on how to list these files starting with a dot?

Files that start with a dot are considered to be "hidden files" in Linux.

To read those files with the ListFile processor, simply set Ignore Hidden Files to false.
