Write a C program using Linux system calls that takes two strings as arguments from the command line. The program should create a new child process, within which it reads characters one by one from the standard input until the end of the file is reached. It should then copy the read lines, starting from the second line, into a newly created file with a name specified as the first argument, replacing each letter with the $\text{'}*\text{'}$ symbol.

In the parent process, redirecting the standard output to the file specified as the second argument, the program should calculate and output, on separate lines, the lengths of the lines from the first file each time. the program should work in Putty
