Rename repository

Browse Source 
Unforunately, It came to my knowledge that this repository
promoted a phenomenon where DevOps interviews became a trivia game
where people think it's normal to throw 20 random short questions
like "what is fork()" or "which tools would you use for each
of the following areas?" and this was not my intention.

To explcitly state this repository doesn't represents real DevOps
interview questions I've decided to rename it.

* Shell reads the input using getline() which reads the input file stream and stores into a buffer as a string

* Shell checks if an expansion is required (in case of ls *.c)
* Once the program in memory, its execution starts. First by calling readdir()
Notes:
* getline() originates in GNU C library and used to read lines from input stream and stores those lines in the buffer
