In computer programming, standard streams are preconnected input and output communication channels between a computer program and its environment when it begins execution. The three I/O connections are called standard input (stdin), standard output (stdout) and standard error (stderr). Originally I/O happened via a physically connected system console (input via keyboard, output via monitor), but standard streams abstract this. When a command is executed via an interactive shell, the streams are typically connected to the text terminal on which the shell is running, but can be changed with redirection, e.g. via a pipeline. More generally, a child process will inherit the standard streams of its parent process.
Users generally know these streams as mediums by which text incoming from an input device and text outgoing to display are handled. As they are used for input and output devices, they generally contain text, a sequence of characters in a predetermined encoding, such as Latin-1 or UTF-8.
The story tells of the king of the sky,
Creator of dreams
On a big book he used to write,
The destiny of all galaxies
Lost in darkness, in his castle, far in the universe
He knew when the world began,
why life ended up
And the reason why events took place
One flies away on the rainbow or inside life
And one's heart's alive...to run...
When the night falls, he'll dominate
And from his throne, magic he'll spread
Present and future have no difference
For the immortal ones
Prisoner of an impossible task
Of life be knew nothing at all
All that's real, the oceans and stars
Are a fruit of his mind
Every soul is important and dreaming he creates
New lives to lose or win
One flies away on the rainbow or inside life
And one's heart's alive...to run...
When the night falls, he'll dominate
And from his throne, magic he'll spread
A race, as an end, the face, that is aging
Where's the mystery behind the dream
The space, I need to open a door, to know if
Heaven will have my replies
One flies away on the rainbow or inside life
And one's heart's alive...to run...
When the night falls, he'll dominate
