Perl is legacy-language territory — and that’s precisely why it still pays: the systems written in it (bioinformatics pipelines, sysadmin tooling, finance batch jobs) aren’t going anywhere, and the people who can maintain them are retiring faster than the code. This guide covers the best Perl courses in 2026 with the honesty the topic deserves.
The short version: Learn Perl 5 By Doing It on Udemy remains the most-taken structured course (4.2★, 18,000+ students — last updated 2023, disclosed below), the free Perl Maven tutorials and official perldoc are genuinely strong, and the right expectation is maintenance-and-scripting competence, not a Perl-first career. There is no recognized Perl certification.

1. Learn Perl 5 By Doing It — Udemy
The most-established structured option: exercise-driven, covering the practical Perl you meet in real systems — text processing, regexes, file wrangling, one-liners. Disclosures, because we make them: 4.2 stars (2,751 ratings) is solid-not-stellar, and the last update was June 2023 — acceptable for a language that itself changes slowly, worth knowing before you buy. Newer alternatives exist on the platform (including a 2025-refreshed “Master Perl Programming”) with thinner track records; check current ratings against this one at purchase time. $9.99–$24.99 on sale, 30-day refund.

2. Perl Maven + perldoc — the free route that professionals actually use
Gabor Szabo’s Perl Maven tutorials are the best free structured Perl material online, and the official perldoc documentation is unusually readable as language docs go. For a working programmer picking up Perl for maintenance duty, this free pair plus a sandbox script is honestly the standard path.
3. Exercism’s Perl track — free practice with mentoring
Exercism’s Perl exercises with volunteer human mentorship cost nothing and fix the loneliest part of learning a legacy language: someone who’ll tell you your solution works but isn’t idiomatic. Pair it with either option above.
Is there a Perl certification?
A third of this page’s search traffic asks, so plainly: no recognized Perl certification exists — no vendor cert, no respected industry credential. Anyone selling a “Perl certification” is selling a completion certificate with ambitions. What convinces employers instead: demonstrated text-processing chops (a small portfolio of real scripts), regex fluency, and comfort reading other people’s decade-old code — the actual job.
Should you learn Perl in 2026? (the honest career math)
Learn it if: you’re inheriting Perl systems (the common case — and the pay for scarce maintenance skills is real); you work in bioinformatics (BioPerl persists) or classic sysadmin environments; or you process text at volumes where Perl one-liners still outrun everything. Skip it if: you’re choosing a first language (Python won that contest — our coding websites guide maps that path) or betting a career pivot on new Perl work, which is rare. Perl in 2026 is a valuable second skill and a poor first one.
The Perl skills that actually get used on the job
Perl maintenance work concentrates in a predictable toolkit, worth weighting in any course: regular expressions (Perl’s native superpower and half of every legacy script you’ll read); text-pipeline one-liners (the idioms that outrun writing a whole program); hash-of-hashes data wrangling (how old Perl structures everything); CPAN literacy (finding and evaluating the module ecosystem’s often-ancient-but-solid answers); and reading untidy code calmly — the unglamorous core competency, since your predecessor’s style will not match the textbook’s. A useful practice source: pick any old open-source Perl tool and annotate one file until every line makes sense.
FAQs
What is the best Perl course?
Learn Perl 5 By Doing It on Udemy is the most-established structured course (4.2 stars, 18,000+ students, last updated 2023 — disclosed). The free Perl Maven tutorials plus official perldoc are the professional-standard alternative.
Is there a Perl certification?
No recognized Perl certification exists. Employers hiring for Perl want demonstrated text-processing and maintenance skills, not paperwork.
Is Perl worth learning in 2026?
As a maintenance and scripting skill, yes — legacy Perl systems persist in bioinformatics, sysadmin, and finance, and scarce maintainers command good rates. As a first language or career bet on new development, no; Python is the modern default.
