Linux tee command

Linux tee command-specific application of the tee command: tee Function Description: Read standard input data and output its content into a file. Syntax: tee [-ai] [-- help] [-- version] [file…] Note: The tee command reads data from the standard input device, outputs the data to the standard output device, and saves it as a file. We can use tee to save the data imported from the pipeline into a file, or even several files at a time. Parameter:-a is appended to an existing file, rather than overwriting it. If the file name given the tee instruction already exists, the content of the file will be overwritten by default. After this parameter is added, the data is added at the end of the file content, and the original content is not deleted.
