我的主目录中有 2 个未知文件（我对它们一无所知）。
我记得在重新安装 ubuntu（升级到 18.04）之前，/home 目录中有太多这样的文件。
昨天我遇到了其中一个，今天我遇到了两个，它们的名字分别是：
hs_err_pid2498.log和hs_err_pid2118.log。hs_err_pid2118.log
的前几行（982 行）：

这些文件是什么？
我可以删除它们吗？（会发生什么？）
直到 2 或 3 个月前我才有这样的文件！
我想当我使用tor服务（搜索或下载）时会出现这些文件，因为我之前没有使用 tor 下载东西（直到 2 或 3 个月前）。
如果是关于安装软件，请注意：4 天前我几乎没有安装任何东西！
答案1
这些是日志文件。它们是在 Java 运行时环境 (JRE) 崩溃后生成的。通常可以放心删除它们，因为它们只是日志文件。
它们包含有关您的系统的详细信息，解释发生了什么以及系统崩溃时的情况。除非您开发了 Java 应用程序，否则它们对您来说真的没什么用。
