Detailed explanation-1: -By default, standard input is the keyboard. It writes to its standard output file. If you invoke a shell command from the shell, a C program, or a REXX program invoked from TSO READY, standard output is directed to your terminal screen by default.
Detailed explanation-2: -STDOUT-the standard output of the shell. By default, this is the screen. Most bash commands output data STDOUT to the console, which causes it to appear in the console. The data can be redirected to a file by attaching it to its contents using the command ยป .
Detailed explanation-3: -Input/Output (I/O) redirection in Linux refers to the ability of the Linux operating system that allows us to change the standard input ( stdin ) and standard output ( stdout ) when executing a command on the terminal. By default, the standard input device is your keyboard and the standard output device is your screen.
