Get files using ListFile but filtering by its name that has a date inside it

mtigua — Fri, 22 Mar 2019 12:24:08 GMT

Hello everyone, please help!

I have files whose name is formed by a date in the format "yymmdd", for example:

TRB_ASE_D190125.txt

TRB_TIT_D190125.txt

I need to get only the files whose names match the current date. For example, if the date was "190125", the 2 subsequent files would match that criterion.

I am using the ListFile processor to get the files and put this regular expression using the "now" function in the File Filter, but it does not work:

^TRB_[A-Z]+_D${now():format('yymmdd')}.TXT

Thanks in advance!

@Mario Tigua

The File Filter property in the listFile processor does not support NiFi Expression Language. If yo float your cursor of the question mark icon to the right of a property name it will display a pop-up window that will tell you if this property will support NiFi expression language.
-

This property expects a java regular expression instead.

Thank you,

Matt
