Standard streams : ウィキペディア英語版 | In computer programming, standard streams are preconnected input and output communication channelsD. M.

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.==Application ==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.These streams can also be chained; the output of a program can then be the input of another one. A well-known example is the use of a pager such as more, which gives the user a way to control which part of the output stream appears on the display.Although the familiar interactive usage is for the standard streams to contain text, they are also often used to transfer arbitrary binary data.

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.
