It is. Very much so.
But the thing that shocks me most about how completely Perl has fallen out of fashion is that nowadays sysadmins will write a hundred-line bash script rather than a five-line Perl script because of the theory that Perl is hard to read.
(Of course, using bash for the shell isn't a good choice because you can't rely on bash being installed).
Personally I reach for Perl as soon as any sort of arithmetic is involved. And even if starting with find(1) is the first choice, it's worth getting to know modules like File::Find because they're way more powerful.
Even alpine has awk installed. docker run --rm alpine awk
