Standard Output and Standard Error
In Linux, there are two primary output streams:
- Standard Output (stdout): This stream is used for regular output, such as the results of a command or program execution.
- Standard Error (stderr): This stream is used for error messages and diagnostic information.
By default, both stdout and stderr are displayed on the terminal. However, you can redirect these streams using special file descriptors and redirection operators.
Linux Error Redirection
Redirection is a feature in Linux which can be used to change the standard input device (keyboard) or standard output device (screen) during the execution of a command. The basic process of any Linux command is that it takes an input and gives output but the standard/input and output can be changed using the redirection technique.
