因此，在 Linux Mint 上多次使用 locate 命令后，我遇到了每个查询在 /timeshift/ 目录中逐行返回结果的问题 - Linux Mint 将其用作操作系统保存点。

如果我使用，比如说，locate anaconda activate.sh，我可能得到的是：

/home/user/.anaconda3/lib/python3.9/site-packages/spyder/plugins/ipythonconsole/scripts
/conda-activate.sh
/home/user/.anaconda3/pkgs/conda-4.12.0-py39h06a4308_0/info/test/tests/test-recipes/activate_deactivate_package/src/etc/conda/activate.d/activate.sh

只有前三个结果是相关的，那么如何排除一个目录呢？

根据我的发现，似乎没有办法使用 plocate 命令在本地执行此操作。但是，仅使用 grep 过滤就有一个解决方法。

用 grep

您可以使用 -v 选项让 grep 输出所有元素不匹配提供的正则表达式，如下所示：

locate anaconda activate.sh | grep -v "^/timeshift"

始终过滤目录

由于 timeshift 目录的时间问题是一个经常重复出现的问题，因此可以为 locate 命令设置别名以自动应用文件夹过滤器。

为此，您需要创建一个自定义函数，然后将 locate 命令作为它的别名：

function locate_without_directory(){
   plocate "$@" | grep -v "^/timeshift"
}

alias locate=locate_without_directory
