更改核心转储的位置 [英] Changing location of core dump

问题描述

我想更改核心转储文件的默认位置，以便每次生成核心转储时都将转至该目录.此外，是否可以通过崩溃文件的名称在该位置保存转储文件?

I want to change the default location of core dump files so that every time a core dump is generated ,it goes to that directory.Also, is it possible to save the dump file by the name of the crashed file in this location?

推荐答案

是的.您可以更改/proc/sys/kernel/core_pattern来定义用于生成核心文件的路径名.有关更多信息，请参见 man core

Yes, it is. You can change /proc/sys/kernel/core_pattern to define the pathname used to generate the corefile. For more, see man core

示例:

echo '/tmp/core_%e.%p' | sudo tee /proc/sys/kernel/core_pattern    # `tee' instead of > so that
                                                                   # opening happens in the
                                                                   # elevated process

将导致所有将来的核心转储都在/tmp中生成并命名为core_[program].[pid]

would cause all future core dumps to be generated in /tmp and be named core_[program].[pid]
