CodeChef SEB Launch Config

This runs one command that gets your computer ready for a CodeChef exam and opens it for you. You don't need to install anything yourself first — it takes care of that.

Windows

• Press Win + R

powershell -NoProfile -ExecutionPolicy Bypass -Command "& ([scriptblock]::Create((irm 'https://seb.cchef.co/seb.ps1'))) -ContestCode 'SEB'"

or

• Open Powershell

& ([scriptblock]::Create((irm 'https://seb.cchef.co/seb.ps1'))) -ContestCode 'SEB'

Mac

curl -fsSL https://seb.cchef.co/seb.sh | bash -s -- "SEB"

Optional: auto-login token

A one-time login token (64 hex characters, valid for 10 minutes, generated by the exam page) can be passed so the candidate is logged in automatically inside SEB. Invalid values are ignored and the candidate logs in manually.

• Windows: append -LoginToken '<token>'
• Mac: pass it as the second argument, e.g. bash -s -- "SEB" "<token>"

Features Implemented

• Closes any apps that might cause problems during the exam (like remote-access/screen-sharing tools) so the exam browser isn't blocked.
• Closes the exam browser if it happens to already be open, so it can start fresh.
• Checks whether you already have the exam browser installed, and whether it's the latest version.
• Installs the exam browser if you don't have it yet, or updates it if your copy is outdated.
• Makes a few small Windows settings changes so antivirus/proxy don't interfere and the exam browser can run smoothly.
• Resets your mouse pointer back to normal, in case a previous exam changed it.
• Opens the exam browser and takes you straight into your contest — no extra clicking needed.
• Closes the command window it ran from automatically.
• Keeps a log file in the background in case anything needs to be looked into later.
