I have written a number of Perl scripts (both CGI and batch) to make up for shortcomings in our ERP system, and to hook up our ERP system to our PDM and financial accounting systems.
Also, I have written a couple of reporting scripts to watch over our Active Directory (look for computers that do not exist any more but still have their AD accounts, stuff like that).
Oh yeah, and a couple of Nagios plugins, too.
For these tasks, there are not many languages that can match Perl in versatility and productivity. It's not the prettiest language, but it's extremely useful.
I don't know about the original poster, but Perl is great for back end development, and there are wrappers for just about every GUI toolkit if you want to go that route.
I use it for command-line utilities, such as static-site-compiler, a blog-compiler, and similar.
Beyond that I use it for microservices, implement REST-APIs, and also for powering whole sites. With the right framework/modules you can do almost anything.
For example I re-implemented the API my home lights use to communicate, allowing me to use cron to turn off lights via the perl interface.
I've used it here and there and don't think its near as bad as people say. Perl6 is a good design, but if the implementation doesn't get sped up, I don't see it taking off.
