The 42 Examshell is the custom terminal-based environment used for all programming exams at 42 School. It automates the distribution, collection, and grading of tasks in real-time. Key Commands & Setup
Accessing the Exam: Log in to the workstation using the temporary exam credentials provided on your screen.
Initialization: Open a terminal and run kinit with your intranet password to authenticate your session.
Launch: Enter examshell to start the interface. It will display your current level, the time remaining, and the subject for your first task.
Submission: Once you have pushed your code to the rendu directory, type grademe in the examshell to trigger the Moulinette for grading. Workflow & Mechanics
Iterative Levels: Exams are divided into levels (e.g., Level 1 to Level 5). You must pass a task to unlock the next level.
The rendu Folder: You must save your files in the specific subdirectory provided within the rendu folder. Files outside this path will not be graded.
Real-time Grading: After running grademe, the shell will either show "Success" (unlocking the next task) or "Failure" (often with a waiting period before your next attempt).
Wait Times: Failing a task typically imposes a cooldown period (e.g., 5, 10, or 20 minutes) that increases with each consecutive failure on the same level. Essential Tips for Success 42 Piscine - Diving In My First Week - DEV Community

At 42, Examshell is the custom terminal-based environment used to deliver and grade your weekly exams. It simulates a strict "exam mode" where you solve coding tasks in levels, pushing your code to a remote repository for automated correction. Logging In to the Real Exam
To access the exam environment on campus, follow these steps:
Initial Login: Use the generic credentials exam/exam to log into the Linux workstation session.
Launch Terminal: Open the terminal and type the command examshell.
Personal Authentication: The shell will prompt for your personal 42 Intranet login and password.
Begin: Once authenticated, the exam timer starts, and your first level assignment is revealed. Navigating the Workspace
The environment is structured into three primary directories in your home folder:
subjects/: Contains the PDF or text file describing your current task.
rendu/: Your local Git repository. You must create the required files and folders exactly as specified here.
traces/: Contains the results and logs from previous grading attempts (if you fail a level). Workflow & Grading The exam follows a linear, "level-up" progression system:
Solve: Write your code (typically a single C function or a small program) in the rendu directory. 42 Examshell
Test: Compile and test your code manually using standard tools like gcc.
Submit: Use git add, git commit, and git push to send your code to the server.
Grade: In the examshell, use the grade command (often just typing grademe) to trigger the Moulinette. Result:
Success: You unlock the next level and a new random subject.
Failure: You get a 0 for that level. You can try again, but there is often a wait time (timeout) before you can request a re-grade. Essential Rules to Remember
No Communication: Any form of chatting, music, or phone use is strictly forbidden.
Final Exits: Once you log out of the examshell or leave the room, your exam is finished.
Grading Precision: The automated grader is extremely harsh; a single typo or Norm error results in a 0 for that task. Practice Resources
Since the real examshell is only available during exam hours, students often use community-made simulators to practice at home:
42_examshell (terminal-42s): A highly popular interactive menu-based simulator for Ranks 02 through 05.
42ExamPractice (emreakdik): A fast, terminal-based shell for grinding specific levels and ranks.
JCluzet's 42_EXAM: A widely used tool to simulate real exam conditions and random task assignment.

For many at 42 School, the Examshell is the most nerve-wracking part of the journey. Whether you are in the Piscine or the Common Core, understanding how to navigate this environment is key to passing. What is 42 Examshell?
Examshell is a custom terminal-based environment designed by 42 to conduct programming exams. It serves as a restricted interface where you receive tasks, submit code, and get graded in real-time by the "Moulinette". How to Get Started
Logging In: You can only log in exactly at the starting time of your exam.
Access: On the cluster Linux machines, open a terminal and enter the command examshell.
Authentication: Use your standard 42 student login and password to enter the exam session. Essential Commands
Once inside, you operate using a few specific commands to manage your exam flow:
status: Shows how much time you have left and your current progress.
subject: Displays the instructions for your current exercise.
grademe: Submits your work for grading. Warning: If you fail, there is often a "wait time" before you can submit again.
finish: Use this when you are done with the exam and want to leave. Pro-Tips for Success
The Level System: You must solve Level 1 to unlock Level 2, and so on. Tasks are assigned randomly at each level. The 42 Examshell is the custom terminal-based environment
Strict Rules: Code is compiled with -Wall -Wextra -Werror. Ensure your code is clean and follows the norm, or the Moulinette will reject it immediately.
Practice Tools: Many students use community-built tools like the 42_examshell practice tool or 42-exam-trainer to simulate the environment before the actual test day.
Stay Calm: If you fail a task, stay in the shell and keep trying unless you are completely stuck. Leaving the shell often ends your exam session. 42 Piscine - Diving In My First Week - DEV Community

If you were in the exam, you would create a main.c to test your function before submitting:
#include <stdio.h>
int ft_strlen(char *str);
int main(void)
char *s = "Hello World";
int len = ft_strlen(s);
printf("Length: %d\n", len); // Expected output: 11
return (0);
If you were looking for a specific subject (like ft_strcpy, ft_strdup, or a harder algorithm like rev_print), let me know and I can provide that specific piece.
The 42 Examshell is the proprietary, terminal-based examination environment used by the 42 Network to evaluate students during the "Piscine" (intensive bootcamp) and the Common Core curriculum. It serves as a gated testing platform where students must solve coding challenges in real-time under strict, isolated conditions. Structure and Workflow
The Examshell operates on a linear, level-based progression system. Students begin at "Level 0" and must successfully pass each task to unlock the next, more difficult challenge.
Authentication: To start, students log into specialized Linux machines in the school clusters using temporary "exam" credentials before launching the examshell command to begin the official session.
The Directory System: The environment typically provides three specific directories:
subjects/: Contains the PDF or text descriptions of the current task.
rendu/: The working directory where students must write and save their code.
traces/: Where logs and error reports are stored after a grading attempt.
Submission: Once a student believes their solution is correct, they must commit and push their code to the provided Git repository and type the grademe command in the shell. Grading and The Moulinette
All exams are graded automatically by a program known as the Moulinette.
Zero Tolerance: The grading system is binary; it provides either a "Success" or "Failure". Even a minor naming error or a single trailing space can result in a failure.
Consequences of Failure: If a student fails a task, they are often given a "waiting time" (timeout) before they can attempt the grade command again, forcing them to double-check their logic thoroughly. The Psychological Element
Beyond technical skills, the Examshell is designed to test a student's adaptability and resilience. The environment is isolated from the internet and outside help, meaning students must rely entirely on their own knowledge and the local man pages (manuals). If a student gets permanently stuck or leaves the cluster, the exam ends immediately. Practice Tools
Because the official Examshell is only accessible during scheduled exam times, the student community has developed various simulators to help peers prepare.
Simulators: Projects like terminal-42s/42_examshell on GitHub replicate the look and feel of the environment, allowing students to practice specific "ranks" (difficulty levels) at home.
Study Focus: Most practice tools focus on Ranks 02 through 05, covering topics from basic C string manipulation to complex algorithms and system-level programming.

Here lies the infamous ft_itoa, ft_split, and print_hex. You need to manipulate linked lists (ft_list_push_back, ft_list_remove_if). You must handle recursion (check_mate or flood_fill).
The Rule: You cannot move to Level 1 until you finish Level 0. You cannot move to Level 2 until Level 1 is perfect. This means if you get stuck on ft_atoi (Level 2), you cannot even see the prompts for Level 3.
