Standard Output, often abbreviated as stdout, is a communication channel used by computer programs to send data to the display or terminal. It is a fundamental concept in programming and operating systems, allowing users to see the results of commands or the output of scripts. When a program runs, it typically generates output that can be displayed on the screen or redirected to a file. This redirection can be done using various commands in Unix or Linux systems, enabling users to manage and store output efficiently for further analysis or processing.
