This will clobber any existing data in file1. Using command < file1 executes command, with file1 as the source of input, as opposed to the keyboard, which is the usual source for ...
In the case of an interactive shell, that is usually the text terminal which initiated the program. The file descriptor for standard output is 1 (one); the POSIX <unistd.h> definition is STDOUT_FILENO; the corresponding C <stdio.h> variable is FILE* stdout; similarly, the C++ <iostream> variable is std::cout.
A console application or command-line program is a computer program (applications or utilities) designed to be used via a text-only user interface, such as a text terminal, the command-line interface of some operating systems (Unix, DOS, [1] etc.) or the text-based interface included with most graphical user interface (GUI) operating systems, such as the Windows Console in Microsoft Windows ...
In these languages, including the line __DATA__ (Perl) or __END__ (Ruby, old Perl) marks the end of the code segment and the start of the data segment. Only the contents prior to this line are executed, and the contents of the source file after this line are available as a file object: PACKAGE::DATA in Perl (e.g., main::DATA) and DATA in Ruby ...
