3: Syntax error: Bad function name

The script is not working 08-May-24.

Sorry folks, this was a quick function that worked 4 years ago. Splunk changes their URLs.

is there a way to fix this? the regex '(?<=data-link=")[^"]+' no longer matches anything.

This isn't the whole script as I only have a very specific use case, it's working for me - You might be able to adapt?

SPLUNK_UF_URL=$(curl -sSlL https://www.splunk.com/en_us/download/universal-forwarder.html|grep -oP '(?<=data-link=")(https://download.splunk.com/products/universalforwarder/releases/.?/linux/splunkforwarder..x86_64.rpm)(?=")')
curl --location -o splunkforwarder.rpm "$SPLUNK_UF_URL"

Hello, I’ve created another script, inspiring myself from this one.
