Pick your week — setup, scoring, and how to submit.

Week 1 · Shell & sysadmin

Shell Wizardry & Sysadmin Sprint

Twelve autograded tasks in a locked-down sandbox. Submit from your terminal with the csot CLI.

Week 1 tasks need a real Linux shell (bash, systemd, nginx). Pick your platform, run the steps, then continue with How it works below.

Linux · Ubuntu, Debian, or Kali

Update packages and install Python + git:

sudo apt update
sudo apt install -y python3 python3-pip python3-venv curl git

Install the contest CLI:

curl -fsSL https://csot-devops.devclub.in/install.sh | bash

Windows · WSL2 (recommended)

In PowerShell as Administrator, install Ubuntu on WSL:
```
wsl --install -d Ubuntu
```
Reboot if prompted. First launch creates your Linux username and password.

Open Ubuntu from the Start menu. Inside WSL, install deps + CLI:

sudo apt update
sudo apt install -y python3 python3-pip python3-venv curl git
curl -fsSL https://csot-devops.devclub.in/install.sh | bash

Do all contest work inside WSL — not PowerShell or CMD.

macOS · Multipass Ubuntu VM

macOS has no systemd. Use a small Ubuntu VM so every task behaves like the grader expects.

Launch a VM:

multipass launch 24.04 --name csot --cpus 2 --memory 4G --disk 20G
multipass shell csot

Inside the VM, install deps + CLI:

sudo apt update
sudo apt install -y python3 python3-pip python3-venv curl git
curl -fsSL https://csot-devops.devclub.in/install.sh | bash
csot login

Every Week 1 task is graded with file submit only (no live sandbox). Put solutions under a folder such as ./solutions/ using the paths below.

02	Count IPs	`csot submit ./solutions -w week-01 -t 02`	02.sh
03	Replace Tabs	`csot submit ./solutions -w week-01 -t 03`	03.sh
04	Rename txt → md	`csot submit ./solutions -w week-01 -t 04`	04.sh
