FS-2: Copy a file

Learn to copy files in C++ on Linux with proper error handling. Overwrite destination files effortlessly. Perfect for System Programming beginners.

Requirements

  • Write a C++ program simple-copy accepting two command line arguments representing source file path and destination file path.
  • Implement proper error handling to account if not all arguments are passed or if one of arguments is not a valid one.
  • Copy the content of the source file into a destination file. If destination file already exists, it should be overwritten.

Expected result

The resulting application should be able to build and execute from command line as follows:

make
./simple-copy source-file destination-file

The final solution should contain a Makefile for the multi-stage build. The Makefile should also contain targets all and clean. It's recommended to have compiler and compiler flags declared as Makefile variables. Alternatively, cmake could also be used instead of make.

FS-1: Read from the file

You need to implement a program that does the same thing as the cat command in the Linux.

FS-3: Secure file deletion

Implement a C++ program that securely deletes a file by overwriting every byte with '\0' before removing it from the filesystem.
