Could you help me use rex to extract end value extensions from field values?

I have field values with the below formats and I need to extract the end value extensions like (cjs, js ..,etc) from them and store them in separate fields. Can anyone help me with this? Thanks

sample=/abc/test/ipts/jquery-1.3.1-vsdoc.cjs 
sample=/abc/test/ipts/jquery-1.3.js

Hello,

try this one:

".*\.(?.*)$"

Tested with:
| makeresults |eval lol="/abc/test/ipts/jquery-1.3.1-vsdoc.cjs " | rex field=lol ".*\.(?<foo>.*)$" | table lol,foo

Hi arrangineni,
try something like this:

\.(?<extension>.*)$

if you already extracted the field sample, you could also use the command

| rex field=sample "\.(?<extension>.*)$"

You can test it at https://regex101.com/r/L5vehV/1

Bye.

This is probably a bit greedy, but it works in regex101.com:

.*\.(?<extension>[a-z]+)

So do you want the js and cjs values from the sample field stored in a separate field (like one named ext) at search time?
