All scripts

Every installer, in plain text. Click any of them to read the exact code before you run it — that is the whole point of this page.

Script	Step	Runs on	What it does
`install_ubuntu_wsl.ps1`	1	Windows	Enables WSL 2 and installs Ubuntu 24.04 LTS
— none —	1.5	Ubuntu	Practice page only; these commands come with Ubuntu
`install_cmds.sh`	2	Ubuntu	Core command line tools
`install_c.sh`	3	Ubuntu	clang and lldb — compile and debug
`install_py.sh`	4	Ubuntu	Python 3 — run a program
`install_java.sh`	5	Ubuntu	Temurin JDK — javac, java, jshell
`report_completion.sh`	5.5	Ubuntu	Tests steps 2–5 and reports the result. Installs nothing.
`install_more_cmds.sh`	6	Ubuntu	The wider toolkit — independent of steps 1–5
`install_binary.sh`	7	Ubuntu	Hex, disassembly, valgrind, make — independent of steps 1–5
`install_uv.sh`	8	Ubuntu	uv: packages, projects, Python versions — independent of steps 1–5
`install_maven_gradle.sh`	9	Ubuntu	Maven and Gradle — independent, but needs the JDK from step 5
`install_all.sh`	2–5	Ubuntu	Runs steps 2 to 5 in order. Does not include 6 to 12.
`install_py_debug.sh`	12	Ubuntu	pdb practice files — independent of steps 1–5
`install_sanitizers.sh`	11	Ubuntu	AddressSanitizer runtime — needs clang from step 3
— none —	10	Ubuntu	Practice page only; jq is already installed by step 2
`common.sh`	—	Ubuntu	Shared helpers the others load. Not run on its own.

Ways to run them

Straight from here

$ curl -fsSL https://aikaryashala.com/system_setup/scripts/install_c.sh | bash

Download first, read, then run

$ curl -fsSLO https://aikaryashala.com/system_setup/scripts/install_c.sh
$ less install_c.sh
$ bash install_c.sh

From a clone of the repository

$ git clone https://github.com/aikaryashala/system_setup.git
$ cd system_setup/docs/scripts
$ ./install_c.sh

How they behave

Idempotent. Re-running one is safe. Anything already present is reported as skip.
Non-interactive. They ask for your password once at the start, then run to the end unattended.
Strict. They stop on the first real failure rather than leaving a half-installed system.
Self-verifying. Each one finishes by printing the version of everything it installed.

Settings you can override

Variable	Script	Default	Effect
`PYTHON_VERSION`	`install_uv.sh`	`3.14`	Which Python uv installs
`UV_TOOLS`	`install_uv.sh`	`ruff`	Tools installed with `uv tool install`
`JDK_VERSION`	`install_java.sh`	`25`	Which Temurin LTS to install
`SKIP_MAVEN` / `SKIP_GRADLE`	`install_maven_gradle.sh`	unset	Set to `1` to leave that build tool out
`STUDENT_NAME` / `ROLL_NUMBER`	`report_completion.sh`	asked for	Skip the prompts
`DRY_RUN`	`report_completion.sh`	unset	Set to `1` to check everything but send nothing
`STEPS`	`install_all.sh`	`cmds c py java`	Which steps to run, in order. Also accepts `more_cmds`, `binary`, `uv`, `maven_gradle`, `sanitizers` and `py_debug`.
`WSL_DISTRO`	`install_ubuntu_wsl.ps1`	`Ubuntu-24.04`	Which distribution to install
`SYSTEM_SETUP_BASE_URL`	all	this site	Where scripts fetch each other from — point it at a fork

For example, to install Python 3.12 and skip Gradle:

$ curl -fsSL https://aikaryashala.com/system_setup/scripts/install_uv.sh | PYTHON_VERSION=3.12 bash
$ curl -fsSL https://aikaryashala.com/system_setup/scripts/install_java.sh | SKIP_GRADLE=1 bash
