确定core文件是由哪个文件产生的方法

1.用gdb打开core文件来确定。如下例子：

[xuzhina@localhost ~]$ ls
asm.list    Desktop    Downloads  Pictures  Templates  vmtoolsd
core.22625  Documents  Music      Public    Videos     vmtoolsd.tar.gz
[xuzhina@localhost ~]$ ls core.22625 
core.22625
[xuzhina@localhost ~]$ gdb -c core.22625

2.用file命令来确定，如下例子：

[xuzhina@localhost ~]$ ls -l core.22625 
-rw-------. 1 xuzhina xuzhina 16257024 Sep  5 23:50 core.22625
[xuzhina@localhost ~]$ file core.22625 
core.22625: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from '/usr/lib/vmware-tools/sbin64/vmtoolsd -n vmusr --blockFd 3'
