This is the anticipated project!!! The simple shell... quite simple when you understand it...
Project between the great
Olaguru (out tutor master)
and
My humble self Oladapsy.
This project took a month to finish, even though the checker was misbehaving
Explanation: we all know the parameter to handle can't be more than 80 character because of betty... so for this reason, a struct was used and this variables were declared using the struct... after which the variables were asigned to each parameter needed to solve the shell... eg.. argc argv issatty and so on..
the code could as well be written in a program but instead it was truncated to 47 functions which made it pass betty and easier to carry out The function used are:
- the usual strcat function: this function helps us to concatenate two strings
- the strcpy function: this function is used to copy two strings, this will be useful when dealing with envs
- the strlen function: this will give the total length of a string... including the null thi will be useful in so many ways and as we define it, it will make the code of the main shorter and we could just xall it whenever we want to use it...
- the strdup: we al know what the sting dup function does... we ill ue all this string function since we cant use them in the string file.
- the putchar/writecharacter: the function will be used to print a character to the standard output
- the atoi function: this function converts a string to an integer
- The realloc function, to reallocate memory.
- The strcmp function: this function is useed to compare two strings to see if they are the same.... as you can see... this will be very useful for our function
- The function tokenize_word or _tokenize: this function collects a word and a delimeter and it tokenizez it using the help of strtok and som string function
