Getting Linux flashcards into Anki

Linux courses are full of short facts that repeat well: command flags, file paths, permission bits and service names. Anki flashcards for Linux work well for this kind of material because each card asks for one fact and the review schedule adjusts to what you forget.

Upload Linux lecture slides, lab handouts, or photos of a terminal cheat sheet.
Get one card per command, flag, or concept, with the question on the front.
Review with spaced repetition in the browser, or export to Anki on the Plus plan.
Students get 40% off with a school email, and no credit card is needed to start.

Example Linux command flashcards

What permissions does chmod 640 give the owner, the group, and others?Owner gets read and write (6), group gets read only (4), and others get no access (0).

Which command shows disk space used by each mounted filesystem?df -h, where -h prints sizes in human-readable units such as G and M.

What does ls -la show that plain ls does not?Hidden files whose names start with a dot, plus long-format details such as permissions, owner, size, and timestamps.

Where do administrator-defined systemd unit files usually go?/etc/systemd/system, which holds local units and overrides, while package-provided units usually live in /usr/lib/systemd/system.

What does the -r flag do in grep?It searches recursively through directories instead of only the file you name.

Generate the full set

Built from your material

Upload PDFs, DOCX or PPTX files, plain notes, or photos of pages. Text recognition reads the images, so handwritten-free printed pages work well.

Spaced repetition built in

Cards come back at growing intervals, so command flags and file paths you miss get shown more often than the ones you already know.

Export to Anki

On the Plus plan, export your cards to Anki and keep reviewing them in the Anki desktop app on Linux, alongside your other decks.

How it works

Upload your Linux notes

Drop in a lecture PDF, a slide deck, a text file of commands, or a photo of a man page printout.

Generate and check the cards

DeckOwl proposes flashcards from the material. Edit or delete any card that is too broad or wrong before you study.

Study or export

Review in the browser with spaced repetition, or export to Anki on Plus and continue there.

Anki runs on Linux, so you can keep your whole review routine on one machine. DeckOwl does not install anything. Start on the free plan with 3 generations a month and study in the browser. If you want the cards in Anki, the Plus plan adds unlimited generations and Anki export.

Check every generated card against your course notes or the official man pages before you rely on it. Keep cards to one command or one idea each, and split long answers into two cards.

Frequently asked questions

How many flashcards should I make for a Linux command course?

Start with the commands you must recognize on an exam or in a lab, usually 40 to 80 cards for a first course. Add more as new topics appear, and remove cards you consistently answer without thinking.

Should one Linux flashcard cover one command or a whole topic?

One command, flag, or idea per card works best with spaced repetition. A card asking for every chmod permission at once is hard to grade honestly, so split it into smaller questions.

Can I export DeckOwl flashcards to Anki on Linux?

Yes, but export to Anki is a Plus feature at $39/year or $7.99/month. The free plan lets you study in the browser, with 3 generations per month and no exports.

Is there a free plan for making Anki flashcards?

Yes. The free plan includes 3 generations per month and browser study with spaced repetition. Exports, including Anki, require Plus.
