The command can be used to capture intermediate output before the data is altered by another command or program. The tee command reads standard input, then writes its content to standard output. It simultaneously copies the data into the specified file(s) or variables. The syntax differs depending on the command's implementation.
In the case of an interactive shell, that is usually the text terminal which initiated the program. The file descriptor for standard output is 1 (one); the POSIX <unistd.h> definition is STDOUT_FILENO; the corresponding C <stdio.h> variable is FILE* stdout; similarly, the C++ <iostream> variable is std::cout.
Then ">" redirects handle 1 to something else, e.g. a file, but it does not change handle 2, which still points to stdout. In the following example, standard output is written to file, but errors are redirected from stderr to stdout, i.e. sent to the screen: command 2 > & 1 > file.
