Most Unix/Linux systems have a command called "tee", which makes
"T-joints" in pipes.
$ tee --help
Usage: tee [OPTION]... [FILE]...
Copy standard input to each FILE, and also to standard output.
-a, --append append to the given FILEs, do not overwrite
-i, --ignore-interrupts ignore interrupt signals
--help display this help and exit
--version output version information and exit
