Description
Introduction
The purpose of this assignment is to become more familiar with the C language.
You will do this by writing a simple Linux shell program that supports directory creation and deletion.
Logistics
You should solve the problem for this assignment individually.
Any clarifications and revisions to the assignment will be posted on the course web page (KLMS).
Project Specification
Your shell program should have the following features
* The command line typed by the user should consist of a command name and zero or more arguments, all seperated by one or more spaces.
* Your shell program should supports following commands:
* The “`ls“` command prints all files and folders in the current working directory.
The printed files and folders should be seperated by exactly ‘one’ space and ended by line break character “`\n“`.
ex) “`”directory1 dirctory2 file1 file2\n”“`
* The “`mkdir“` command creates directory.
* The “`rmdir“` command deletes directory.
* The “`cd“` command changes the current working directory to target directory.
* The “`cd ..“` command changes the current working directory to upper directory.
