DevCards: Git & Linux Commands

You know the command exists. You just can't remember the exact flag when you need it.

DevCards is a flashcard app for the commands you reach for every day at the terminal. Swipe through Git, Unix, Docker and HTTP status codes, recall what each one does, and flip the card to check yourself. It is built for the way you actually learn this stuff: a little at a time, between builds, on the train, whenever you have a minute.

Every card goes past the one-line definition. You get the command, what it does, a real situation where you would reach for it, and a copy-of-real example you would actually type. So you are not memorizing trivia, you are wiring up the muscle memory you want when you are deep in a rebase or chasing a 502.

WHAT YOU CAN STUDY

Unix and Linux: navigation, file permissions, grep, find, process management and the pipe tricks that save you real time every day.

Git: the everyday commit and branch flow, plus the stash, rebase, reset and reflog moves you only half-remember under pressure.

Docker: building images, running containers, volumes, logs and the cleanup commands that keep your disk from filling up.

HTTP status codes: what each one actually means and when you would send it, from the common 2xx and 4xx down to the ones you have to look up every time.

STUDY THE WAY YOU WANT

Review weak: drill only the cards you have not locked in yet, so you spend your time where it counts.

Study all: go through a whole deck front to back.

Common only: stick to the everyday commands first.

Advanced only: push into the deeper flags and edge cases once the basics are second nature.

Random ten: a quick set when you only have a couple of minutes.

TRACKS WHAT YOU KNOW

Mark each card as "I know this" or "still learning" and DevCards remembers per card. Your progress is saved right on the device, so weak cards keep coming back until they stick. Finish a session and you get a clean summary: how many cards you reviewed, how many you mastered, and your mastery rate for the deck.

BUILT FOR THE TERMINAL

Dark green-on-black, monospace, the look you already stare at all day. Swipe to move, tap to flip. No sign-up, no account, nothing to configure. It all works offline, so it runs the same on the subway as it does at your desk.

Whether you are studying for a DevOps interview, getting comfortable on the command line, or just tired of reaching for the same cheat sheet, DevCards turns the reference you keep looking up into something you actually remember.

Open it, swipe a few cards, close it. Do that for a week and watch how much less you reach for Google.
