This is a simple shell program that allows you to execute both executables and built-in commands. It provides a basic command-line interface where you can enter commands and receive corresponding output.
The shell supports the following features:
- Execution of external executables: You can run any executable file by typing its name and providing any necessary arguments.
- Built-in commands: The shell provides a set of built-in commands that can be executed directly within the shell.
- Environment variables: The shell supports environment variables and allows you to set, get, and modify them.
The current implementation of the shell has the following limitations:
- Redirecting: The shell does not support advanced input/output redirection techniques like
>(output redirection to a file) or|(piping output to another command). - Shell piping: The shell does not support piping the output of one command as input to another command.
- Aliases: The shell does not provide a built-in mechanism for defining and using command aliases.
To use the shell, follow these steps:
- Clone the repository:
git clone https://github.com/your-repository.git - Compile the source code:
gcc shell.c -o shell - Run the shell:
./shell
Once you have the shell running, you can enter commands and press Enter to execute them. Here are some examples of how to use the shell:
- Run an executable:
./my_executable arg1 arg2 - Execute a built-in command:
cd /path/to/directory - Set an environment variable:
set VAR_NAME=variable_value - Get the value of an environment variable:
echo $VAR_NAME - Run a shell script:
./my_script.sh
