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.
