原始 .bashrc 出现“语法错误：文件意外结束”

我很茫然。

Kubuntu 18.04.4 LTS

已经运行良好好几年了。

bash: .bashrc: line 118: syntax error: unexpected end of file当我打开终端窗口时，我突然得到“ ”。

我很久没有修改过这个文件了。我仍然在寻找任何缺失的结束语、缺失的引文等。但我什么也没找到。

我检查了行尾是否符合正确的 UNIX 风格，结果确实如此。

奇怪的地方就在这里：我最终将原始文件从复制/etc/skel到了~/……但也没有运气！

这是我当前的内容~/.bashrc（就像我说过的来自发行版的原始内容一样，它仍然给我同样的错误）。

更新： 这始终是用户错误，始终如此。

根据@bhordupur的建议，我set -x在文件顶部添加了。我不会用输出污染线程，但它让我看到问题出在my .bash_aliases（它被调用.bashrc，顺便说一句，我也检查过它）。我定义了一个名为的别名fi，如果你相信的话。所以当然这被解释为结束语if。更改了别名的名称。问题解决了。

从 bash 包中提取原始 .bashrc 文件：

$ apt-get download bash && \
  dpkg-deb -x bash_*_*.deb bash
