tee [,OPTION/]... [,FILE/]...
Copy standard input to each FILE, and also to standard output.
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.
