八度：禁用八度工作区崩溃文件

Question

如何在 Octave 崩溃时禁止在工作目录中创建八度工作区文件？

我在 octave_core_file_options() 中没有看到任何禁用它的选项。这可能吗？也许通过在终止时自动删除文件来进行黑客攻击？（问题是 .octaverc 在开始时运行）

Answer 1

您要找的是crash_dumps_octave_core:

Query or set the internal variable that controls whether Octave tries to save all current variables to the file 'octave-workspace' if it crashes or receives a hangup, terminate or similar signal.

只是为了完整起见，这一系列函数（octave_core_file_limit、octave_core_file_name 和 octave_core_file_options）在名称上使用 "octave_core" 而不是 [=37] 的原因=], 是在旧版本上文件的默认名称是 "octave-workspace".

你怎么能自己找到这个？

根据你的问题，你已经知道 octave_core_file_options。如果您看到该功能帮助文本的底部，您会发现：

See also: crash_dumps_octave_core, octave_core_file_name, octave_core_file_limit.
通过调用 doc octave_core

可以使用lookfor命令搜索函数：
