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.
