This is a colaboration project between two sfotware development students at Holberton School from Cohort 12, This project is about to create an own simple shell
Is an standard command interpretation for system.
- holberton.h Where prototypes and global variables are stored.
There are some functions used to run our simple shell
-
_myexit Function that check command line to exit shell.
-
signal_c Function that make shell ignore input signal Ctrl + C.
-
_myenv Function tht prints the environment variables separated
-
_getenv Functions that find the env variable name
-
_getline Function that get line command line from the prompt.
-
splitline Function that get line command line from the prompt.
-
execute_process Function that execute a process.
-
_which Function that search for a command in the directories.
-
_link Function that built linked list with directories stored in the environment.
-
_add_nodeint_end Function that add a new string to a node at the end.
-
free_list Function that frees a list_t list.
-
free_array Function that frees an array.
-
_strlen Function that find the length of a string.
-
_strcat Function that concatenate directories with the 1st position of the array.
-
_strtok Function that breaks a string into a sequence.
- Allowed editors: vi, vim, emacs
- All the files will be compiled on Ubuntu 14.04 LTS
- The C programs and functions will be compiled with gcc 4.8.4 using the flags -Wall -Werror -Wextra and -pedantic
- All the files should end with a new line
- A README.md file, at the root of the folder of the project is mandatory.
- The code should use the Betty style.
- The shell should not have any memory leaks.
- No more than 5 functions per file.
- All the header files should be include guarded.
- Use system calls only when is needed.
