This is a file descriptor that represents the standard error stream, which is used to write error messages and diagnostic output. What is a file desciptor? The output stream is referred to as standard output; And the error stream is. It is by convention that, unix system shells associates the file descriptor 0 with standard input of a process, file descriptor 1 with standard output, and file descriptor 2.
