Minishell is a simple shell implementation in C that mimics the behavior of a Unix shell. It supports basic shell functionalities such as command execution, environment variable management, and redirections.

minishell> echo $ARG

minishell> export ARG="ch" && "e$ARG"o $ARG
ch
minishell> export ARG="ch" && "e$ARG"o $ARG$ARG && ls
chch

minishell> export ARG1="nano" && export ARG1="roll" | echo $ARG1
nano

• Execute commands with arguments
• Handle environment variables (export, unset, env)
• Built-in commands: cd, echo, pwd, exit
• Input/output redirections (>, >>, <, <<)
• Pipe support (|)
• && and || operators support
• Signal handling (e.g., Ctrl+C to interrupt)
• Error handling and reporting

• GCC or Clang compiler
• GNU Make
• Readline library

To build the project, run the following command:

make

This will compile the source code and create the minishell executable.

To start the shell, run the following command:

./minishell

You should see a prompt where you can start typing commands.

To run the provided tests, execute the following script:

./test.sh

Minishell supports the following built-in commands:

• cd [directory]: Change the current directory to the specified directory.
• echo [string ...]: Display the specified string(s) to the standard output.
• pwd: Print the current working directory.
• export [name[=value] ...]: Set environment variables.
• unset [name ...]: Unset environment variables.
• env: Display the current environment variables.
• exit [status]: Exit the shell with the specified status code.
• Additionally, you can use standard Unix commands and features such as:
  • Input/output redirections (>, >>, <, <<)
  • && and || operators
  • Pipes (|)
