It's there in the documentation; In the case of passing in an "options" hashref, the wanted function is one of the key/value pairs in that hashref.

Hi Dave, thanks for the reply. i did not understand the "follow => ...," part. what should the "...," section include? thanks, Yaron.

The SYNOPSIS section from the documentation for the module shows exactly how to do what you're asking in this thread, and shows an example of what follow should contain:

Here's the third example in the SYNOPSIS section:

use File::Find;
find({ wanted => \&process, follow => 1 }, '.');

Dave

A true value if you want the option to take effect, a false value otherwise. See follow.

What part of "there in the documentation" don't you understand? Learning to use documentation is an important part of learning to write code, or indeed doing many things in life.

Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond

Its not a direct answer but if you know how to get the find command to do what you want the find2pl program that comes with Perl can be useful getting sample code. Might also look at File::Find::Rule which has a bit nicer api.

Hi Yaron,

You've already received some excellent answers!

In case it helps you improve your Perl skills, I've cobbled together File::Find References. After you've had time to read and digest them, please feel free to post your early attempts at using File::Find here for feedback.

If you put in the effort to create a SSCCE, you are certain to receive lots of useful advice that will improve your Perl skills.

👁️🍾👍🦟
