This project was completed by Reginah Shikanda and Sosthene Timi as part of the ALX SE collaboration project requirement. A shell is a program that provides a user an interface for accessing the operating system's services. It allowes users to interact with the computer's operating system through a command-line interface and execute various commands and operations. This simple shell project is an imitation of the bash but with limited features.
- Displays a prompt and waits for a user to type a command. The command line always end with a new line
- The prompt is displayed each time a command has been executed.
- The commands line are simple, no semicolons, no pipes, no redirections.
- The command lines are made of only one word.
- If an executable cannot be found, print an error message and display the prompt again.
- It handles Errors
- It handles the EOF condition (Ctrl+D).
- It handles command lines with arguments, handles the PATH, implements exit built-ins and handles comments.
The Customised shell will be compiled using gcc -Wall -Werror -Wextra -pedantic -std=gnu89 * .c hsh
- cd - command that changes directory
- unsetenv - command that removes an environment variable.
- setenv - command that initializes a new environment/modifies existing one
- exit - command that exits a simple shell
- env - command that list current environment variables
- pwd - command that prints the path of the current working directory.
- Semicolon(;) - serves as a command seperator that enables the execution of multiple commands on a single line by placing the semicolon between each command.
- Harsh - Using a word starting with a harsh symbol in a CLI, designates the rest of the characters on that line as a comment, causing them to be ignored when the command is executed.
