configuration - Octave :禁用 Octave 工作区崩溃文件

Question

当 Octave 崩溃时，我如何禁止它在工作目录中创建 octave-workspace 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

你要找的是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.

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)的名称中带有“octave_core”的原因而不是“octave_workspace”，在旧版本中，文件的默认名称是“octave-workspace”。

你怎么能自己找到这个？

1. 根据您的问题，您已经知道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.

2. 通过调用 doc octave_core 查看有关此函数的手册部分

3. 可以使用lookfor命令来搜索函数:
