Here are a few things that you should know about using regular expressions in. You can also use regular expressions with evaluation functions such as match and replace. You can use regular expressions with the rex and regex commands. Here's an example:Įither method returns a field called ipclass that contains the class portion of the IP address.I have a whole bunch of these and I need what comes after ?desktop= and before the " Splunk Search Processing Language (SPL) regular expressions are PCRE (Perl Compatible Regular Expressions).
