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