Bash provides a command to exit a script if errors occur, the exit command.

If N is omitted the exit command takes the exit status of the last command executed.
What to do when you get a SIGPIPE error in C?
You generally want to ignore the SIGPIPE and handle the error directly in your code. This is because signal handlers in C have many restrictions on what they can do. The most portable way to do this is to set the SIGPIPE handler to SIG_IGN. This will prevent any socket or pipe write from causing a SIGPIPE signal.
How to avoid SIGPIPE signals in C #?
The most portable way to do this is to set the SIGPIPE handler to SIG_IGN. This will prevent any socket or pipe write from causing a SIGPIPE signal. To ignore the SIGPIPE signal, use the following code:
How to prevent sigpipes ( or handle the crash properly )?
SIGPIPE is genereated if I try to write to the same broken socket second time. So you don’t need to ignore SIGPIPE if this signal happens it means logic error in your program. What’s the best practice to prevent the crash here? Either disable sigpipes as per everybody, or catch and ignore the error.
Can you ignore the write bits in a SIGPIPE?
When you go and read that, you will get back 0 bytes, which is how the OS tells you that the file handle has been closed. The only time you can’t ignore the write bits is if you are sending large volumes, and there is a risk of the other end getting backlogged, which can cause your buffers to fill.
