我的主文件夹中恰好有 169 个空文件夹，.bash_history-*.tmp这些文件夹是在我不知情的情况下于同一天（2021 年 4 月 16 日）创建的。文件只有所有者的读写权限。我不确定是什么导致了这种情况的发生。在我 5 年的 Linux 之旅（桌面和服务器）中从未发生过这种情况。更奇怪的是，我的默认 shell 不是 bash 而是zsh.如果有人能帮助我弄清楚到底发生了什么（如果可能的话）或者以前发生在其他人身上，那就太好了？先感谢您。这里是

仅供参考：有人帮我找到了类似的帖子archlinux论坛但它没有回答我的问题。
答案1
源代码bash（在 Debian 上可用）使用文件中的apt-get source bash函数写入其历史文件。它创建一个临时文件，将历史行写入其中，然后用它来替换实际的历史文件history_do_writebash-5.0/lib/readline/histfile.c
tempname = (overwrite && exists && S_ISREG (finfo.st_mode)) ? history_tempfile (histname) : 0;
output = tempname ? tempname : histname;
...
if (rv == 0 && histname && tempname)
rv = histfile_restore (tempname, histname);
在许多地方写入可能会失败，在这些情况下，临时文件将被取消链接（删除），原始文件将被保留。
但是，您在路过的评论你发动了叉子炸弹。这很可能是这些临时文件的根本原因。由于不受控制的 forkbomb 触发了极端的内存和进程压力，有可能bash无法获得足够的临时内存来完成此恢复过程，并且在尝试更新期间简单地崩溃了。 （请注意，这不是铁证，只是一个假设。）
如果您处于用户可能会运行 forkbomb 的环境中，那么这是值得的启用资源控制。
答案2
不可能肯定地说，但很可能有些东西改变了HISTFILE环境变量，然后调用 bash （或者可能是其他一些readline基于文件，但问题是为什么$HISTFILE会包含.bash-history）。
这听起来像是您在单元测试（套件）中要做的事情。
我已经研究了 bash 源代码几分钟了，看起来没有任何地方会偏离默认值，$HOME/.bash_history除非通过HISTFILE.
答案3
这是搜索中出现的 SO 帖子，所以我将答案放在这里。
这很可能是超过的结果$HISTSIZE。
要设置为 20,000 个条目，请将其放入您的.bashrc：
export HISTSIZE=20000
要使无限留空：
export HISTSIZE=
