pee(1) - Linux man page
Name
pee - tee standard input to pipes
Synopsis
pee ["command"]
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.
