Simple Shell is a basic UNIX command line interpreter implemented in C. It provides a simple interface for users to execute commands, handle built-in functionalities, and perform variable substitution. The shell supports various features such as executing external commands, handling built-in commands, environment variables, aliases, and file input.
- Execute external commands
- Handle built-in commands: exit, env, cd, alias
- Perform variable substitution using environment variables (
$VAR) and special variables ($ ?, $$) - Support command execution from a file
- Handle comments (#) in command input
- Support command separation with ;, logical operators && and ||
- Change the current working directory and update the PWD environment variable
- Print and manage aliases
To compile the shell, run the following command:
gcc -Wall -Werror -Wextra -pedantic -std=gnu89 *.c -o hshTo run the shell in interactive mode, use:
./hshTo run the shell in batch mode with a file, use:
./hsh [filename]Once the shell is running, you can type commands and execute them. Here are some examples:
$ ls
$ pwd
$ cd /path/to/directory
$ alias list="ls -l"
$ list
$ exitFor more information on the supported commands and usage, refer to the documentation.
The documentation for the Simple Shell project are available in the ressources provided by ALX holberton school. It includes detailed explanations of the shell's features, supported commands, and usage examples.
