The tee command is used to redirect data to a file and, on the other hand, to provide a copy of the redirected data as a stdin for subsequent commands. To put it simply, redirect the data to a given file and screen.

1. Brief introduction to Command

After reading data from standard input, the tee command redirects the data to a given file and standard output. There can be multiple files for a given file.

Because tee means the letter T, data flows in from the left (standard input), shunts output from the right (standard output) and below (file), and the shape of the letter T vividly illustrates the flow direction of the data, so the command is named tee. The process of data flow is shown in the following figure.
