If the user does not provide exactly 2 command line arguments, print Error: must provide exactly 2 arguments to stderr, and exit the programIf the file does not exist, print Error: '<filename>' cannot be found to stderr, and exit the program

Use 2> to redirect stderr to a file.

Write a program that copies the content of a file to another file.Usage: cp file_from file_toif the number of argument is not the correct one, exit with code 97 and print Usage: cp file_from file_to, followed by a new line, on the POSIX standard errorif file_to already exists, truncate itif file_from does not exist, or if you can not read it, exit with code 98 and print Error: Can't read from file NAME_OF_THE_FILE, followed by a new line, on the POSIX standard errorwhere NAME_OF_THE_FILE is the first argument passed to your programif you can not create or if write to file_to fails, exit with code 99 and print Error: Can't write to NAME_OF_THE_FILE, followed by a new line, on the POSIX standard errorwhere NAME_OF_THE_FILE is the second argument passed to your programif you can not close a file descriptor , exit with code 100 and print Error: Can't close fd FD_VALUE, followed by a new line, on the POSIX standard errorwhere FD_VALUE is the value of the file descriptorPermissions of the created file: rw-rw-r--. If the file already exists, do not change the permissionsYou must read 1,024 bytes at a time from the file_from to make less system calls. Use a bufferYou are allowed to use dprintf

Write a C program that prints exactly and that piece of art is useful" - Dora Korpar, 2015-10-19, followed by a new line, to the standard error.You are not allowed to use any functions listed in the NAME section of the man (3) printf or man (3) putsYour program should return 1Your program should compile without any warnings when using the -Wall gcc option
