Hi,
For some time now some files have been being created in my /home directory (fedora 9).
Their format is always:
core.xxxxx

where xxxxx are some digits
I deleted them this morning, so I don't know if they are the same size.
It just created another one half an hour ago:

I can't view it as it's a binary file

How can I track down which process/program created it?
I hope my box hasn't been hijacked...
I'm aware that you'll need more info to determine the source of it, but
I'm not entirely sure what exactly you need, so please specify it.

thanks very much

Type:

file ~/core.*

and file will tell you the names of the programs that are crashing.

See also to learn something more about core files and system customization (that is customize the name of the core files, change their default location and so on). Also have a look at this thread, in particular posts #3 and #4 (self-citation).

ok, thanks guys
This turned out to be an nx client crashing.

thanks again
