If you have some bug (unexpected error scenarios) in your program and it is resulting in crashing your program, you should be able to debug why the program has crashed. For this purpose the Operating system will copy process stack into a file called core dump file.

如果你的程序中有一些错误(意外的错误情况),并导致程序崩溃,你应该能够调试程序崩溃的原因。为此,操作系统将进程堆栈复制到名为core dump file的文件中。

ulimit , is a system command.

ulimit,是一个系统命令。

ulimit -c unlimited, command used to set the core dump file size to unlimited. Instead of unlimited you can specify the maximum limit of the core dump file size also.

ulimit -c unlimited,用于将核心转储文件大小设置为无限制的命令。您也可以指定核心转储文件大小的最大限制,而不是无限制。

for more information type man ulimit
