TEE(1)

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  diagnose errors writing to non 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'. The default operation when --output-error is not specified, is to exit immediately on error writing to a pipe, and diagnose errors writing to non pipe outputs.
