I certainly have, and might have written a few of those myself.

But this doesn't make this approach inherently wrong or obsolete. The programmer is wrong for trying to use the tools beyond their capabilities. Where that line is drawn is subjective, as is the concept of maintainability, but if you feel that you're struggling to accomplish something, and that it's becoming a chore to maintain, the path forward is choosing a more capable tool, like a programming language.

I think we are actually mostly in agreement there then.

Perl was invented because the gap from shell to more capable languages was (and is) really big. Languages like Python and Ruby didn’t exist yet, and Perl had a really, really strong sweet spot in text processing.

Still does.

Since Ruby took the best bits of Perl what advantage does Perl retain?

>> what advantage does Perl retain?

Ubiquity, speed, and conciseness.

Perl is usually installed by default on Linux and Unix systems. Ruby might be there, it depends.

Perl is faster than Ruby. Ruby has been one of the slower scripting languages. But Ruby has been working on performance improvements in the past few releases. I have not seen any benchmarks of the current Perl versus the current Ruby, so this may have changed.

Perl is more concise than Ruby allowing more functionality for less code.

I don't know about conciseness. Ruby excels here. As for speed it's useful to distinguish between startup and runtime.

The JVM would like a word. (It has slow startup, but can be very fast at runtime due to JIT optimization and cacheing.)

Scripts should start and run quickly.

Ruby has historically been fairly slow which is why Ruby 3 focused heavily on performance. It has been improving a lot, but I have not seen any benchmarks against other programming languages.

I used Perl then Ruby as my main language for almost a decade each. These days, I don't really write Ruby anymore; I moved on to Elixir and never looked back. But I still find myself using Perl on the command line, in contexts where Awk or Sed would also make sense. Ruby never optimized for the one-liner case IMO.

I don't understand your last point. `ruby -e` has excellent parity with `perl -e`.
