diagnose errors writing to non pipes
set behavior on write error. See MODE below
display this help and exit
output version information and exit
MODE determines behavior with write errors on the outputs:
diagnose errors writing to any output
diagnose errors writing to any output not a pipe
exit on error writing to any output
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.
