This project was developed as part of a course on Centralised Operating Systems during my first year at ENSEEIHT.

Goal

The aim of this project was to understand and reproduce a (mini) shell. This is a program that provides an interface to operating system functions.

Usage

How to use the minishell

git clone https://github.com/XNxa/Minishell.git
cd Minishell
make all
./minishell

How to run the test file

Please note: the tests are not exhaustive

git clone https://github.com/XNxa/Minishell.git
cd Minishell
make all
./minishell
sh test.sh

Features

• Internal commands on the minishell

  • exit : exit the program
  • cd : change directory, similar to the bash command
  • lj : List processes/jobs currently running
  • sj [id] : Pauses the "id" process
  • bg [id] : Restart a paused process in the background
  • fg [id] : Restart a paused process in the foreground

• External commands : The program can run any command installed on the system (More specifically, installed on the shell from which you run minishell). For example, ls, git, whoami, ...

• Pipes : The minishell is able to handle pipes. You can try with echo "Hello World" | wc -w, you should obtain 2.

• Redirecting : The minishell is also able to handle redirections. You can try with echo "Hello World" > newfile.

• Run program in background : You can run any programme in the background by adding & to your command line.
