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
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.
