man5/core.5 Piping core dumps to a program: ulimit -c restrictions does not apply when using pipe

man5/core.5 Piping core dumps to a program: ulimit -c restrictions does not apply when using pipe

[Per Böhlin]

The man page for coredumps:
http://man7.org/linux/man-pages/man5/core.5.html

In section: Piping core dumps to a program
should probably have a bullet explaining that the size limit imposed by ulimit -c does not apply when using the pipe-mechanism.

Thanks,

Thanks. From my reading of the kernel source, I agree.
I added the following text to the page:

       *  The RLIMIT_CORE limit is not enforced for core dumps  that  are
          piped to a program via this mechanism.

Cheers,

Michael
