NAME
tee - read from standard input and write to standard output and files

SYNOPSIS
tee [OPTION]... [FILE]...

DESCRIPTION
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

-p operate in a more appropriate MODE with pipes.

--output-error[=MODE]
set behavior on write error. See MODE below

--help display this help and exit

--version
output version information and exit

MODE determines behavior with write errors on the outputs:
warn diagnose errors writing to any output

warn-nopipe
diagnose errors writing to any output not a pipe

exit exit on error writing to any output

exit-nopipe
exit on error writing to any output not a pipe

The default MODE for the -p option is 'warn-nopipe'. With "nopipe" MODEs, exit immediately if all outputs become
broken pipes. The default operation when --output-error is not specified, is to exit immediately on error writ‐
ing to a pipe, and diagnose errors writing to non pipe outputs.
