The Gates of Shell, by Spencer Cheng, featuring Julien Barbier Project to be done in teams of 2 people (your team: Prince Magutshwa, Youssef Bouryal)
At the end of this project, you are expected to be able to explain to anyone, without the help of Google:
- Allowed editors: vi, vim, emacs
- All your files will be compiled on Ubuntu 20.04 LTS using gcc, using the options -Wall -Werror -Wextra -pedantic -std=gnu89
- All your files should end with a new line
- A README.md file, at the root of the folder of the project is mandatory
- Your code should use the Betty style. It will be checked using betty-style.pl and betty-doc.pl
- Your shell should not have any memory leaks
- No more than 5 functions per file
- All your header files should be include guarded
- Use system calls only when you need to (why?)
*There should be one project repository per group. If you and your partner have a repository with the same name in both your accounts, you risk a 0% score. Add your partner as a collaborator. *
More Info Output Unless specified otherwise, your program must have the exact same output as sh (/bin/sh) as well as the exact same error output. The only difference is when you print an error, the name of the program must be equivalent to your argv[0] (See below) Example of error with sh:
$ echo "qwerty" | /bin/sh /bin/sh: 1: qwerty: not found $ echo "qwerty" | /bin/../bin/sh /bin/../bin/sh: 1: qwerty: not found $ Same error with your program hsh:
$ echo "qwerty" | ./hsh ./hsh: 1: qwerty: not found $ echo "qwerty" | ./././hsh ./././hsh: 1: qwerty: not found $

- README.md - description about the project repo
- man_1_simple_shell - is the man page for the shell we are going to write.
- AUTHORS - file at the root of your repository, listing all individuals having contributed content to the repository.
- main.h - is the header file which contains the standared header file and prototype of o function used in the program.
- main.c - initialize the program with infinite loop by call the prompt function
- prompt.c - it use getline system call to read the input from the user and run infinite loop with fork to keep prompt going.
- special_character - It identiies if the special inputs such as if the frist input is slash,the user typed exit or env...
- string.c -it handles the strings(string length, write string,find string in directory,concatane strings....)
- cmd.c - it finds the command the user entered.
- execute.c - execute the command.
