pee
Table of Content
Description
pee is like tee but for pipes. Each command is run and fed a copy of the standard input. The output of all commands is sent to stdout.
Note that while this is similar to tee, a copy of the input is not sent to stdout, like tee does. If that is desired, use pee cat ...
Installation
In Debian and for Debian based systems you will find it in the package moreutils, which can be installed with apt.
$ apt install moreutils
