NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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 writing to a pipe, and
       diagnose errors writing to non pipe outputs.
