What is ez50?

ez50 is a community tool that makes working with CS50 problem sets EASY (or ez). Instead of copying and pasting commands from harvard.edu, finding the right files, and extracting them manually, you just type one command and you're ready!

Key features:

• One-Command Setup: Download and extract problem sets instantly
• Smart Suggestions: Made a typo? ez50 suggests what you probably meant
• Multiple Years: Access different versions of the same problem set
• Auto-Updates: The tool checks for updates automatically
• No Hassle: No configuration needed, just install and use

Commands

Download a Problem Set

ez50 world

This downloads the problem set, sets up your folder, and gets everything ready to go!

Check Your Solution

$ ez50 check world
# short version:
$ ez50 c world

Runs the official check50 tool to test your code.

Submit Your Solution

ez50 submit world
# short version:
ez50 s world

Submits your problem set using the official submit50 tool.

Nice Features:

I'm in a different year!

All commands support the --year or -y option:

ez50 world --year 2024
ez50 check world -y 2025

I don't trust you!

Use --dry-run or -dr to see what commands WOULD execute, without actually executing them:

$ ez50 world --dry-run
╭─ Info ─────────────────────────────────────────────╮
│ Dry Run: The following commands WOULD be executed: │
╰────────────────────────────────────────────────────╯
╭─ Info ───────────╮
│   > mkdir world  │
│   > cd world     │
│   > code hello.c │
│   > ls           │
╰──────────────────╯

Does it include my course?

ez50 supports all CS50 problem sets! This includes: CS50x, CS50P, CS50WEB, CS50SQL, CS50AI and CS50R

Check out the full list of supported problems in the data.json file.

all: We don't include CS50: Law, CyberSecurity and Scratch. Because those don't have problem sets.

What else?

ez50 magically suggests what you probably meant:

$ ez50 numbers
╭─ Error ───────────────────────────────────────────╮
│ Problem 'numbers' not found.                      │
│ Perhaps you meant 'numb3rs' instead of 'numbers'? │
╰───────────────────────────────────────────────────╯

About

This is an unofficial, community-built tool. It is NOT affiliated with, endorsed by, or associated with Harvard University or the CS50 course. It's made by Students for Students to save time on repetitive tasks.

The official CS50 tools (check50, submit50) are still used under the hood, ez50 just makes them easier to use.
