...is a core dump.

What is a core dump?

How does a person respond to one?

Is there anything I should do (or not do) after getting one?

13 responses total.

Is that a candidate for the default .login? Those that know enough to
want core, would know enough to look at .login and remove it.

 On a certain other system the staff sometimes looks at core dumps even if
the user isn't expert enough to use them.  And I think they also have a
demon that looks for and removes core dumps that support doesn't need.  I
know little or nothing beyond that, except that that system has a disk
space quota (500K) and charges $$$ if you exceed it (It's an officially
for-profit system with mandatory fees).  Are core dumps here likely to be
of use to the system gurus?

I think that if some supported utility is giving problems and someone wants
samples to try to debug, they're likely to either generate them themselves
or *ask* people to not delete the core dumps from that utility.  Without such
a posted request, or if it's a program of your own that crashes, I'd go
ahead and delete the core file.

limit is not supported by sh.

Re 6: are you saying that it's not important to limit coredumpsize
or remove core dumps because they will automatically be removed soon?

If I were to create a file named 'core' which was not a core dump, would
it be removed soon too?

Fwiw, I have the command    rm core   in my  .logout  file which
most often says, "file not found" or someting similar every time
I log out, but, hey, it gets rid of core files whenever they ARE found
in my filespace.
  
I thnk it's a good idea. Oh, and I just sent email about 11,000,000
of (seemingly) useless core files that have beena round since (the
oldest) Mar 28. 
  
Sometimes core files MUST be kept for analysis and diagnostic work,
in which case the perns rename them.

either way works, probably should preempt the corefile creation though, 
good idea.
