The Simple Shell is a basic UNIX command line interpreter that allows you to execute simple commands with arguments. It's a minimalistic implementation that provides a basic prompt, parses commands and arguments, and executes them using the execvp() function.
To use the Simple Shell, first compile the program by running the following command:
gcc -Wall -Werror -Wextra -pedantic *.c -o simple_shellThis will compile all the C files in the directory and create an executable called simple_shell. You can then run the program using the following command:
./simple_shellThis will start the Simple Shell and display the prompt:
simple_shell$From here, you can type in a command followed by its arguments and press Enter to execute it. For example, to list the contents of a directory, you can use the ls command:
simple_shell$ ls /usr/binThe Simple Shell will parse the command and its arguments, and execute it using execvp(). If the command is not recognized, the shell will display an error message and display the prompt again.
To exit the Simple Shell, simply type exit and press Enter. This will terminate the shell and return you to the command line.
The Simple Shell has some limitations and does not support advanced features such as pipes, redirection, or special characters. It is a basic implementation designed for educational purposes and can be used as a starting point for more advanced shell programs.
