因此，在 Linux Mint 上大量使用locate命令之后，我遇到了每个查询都在/timeshift/目录中返回一行又一行结果的问题 - Linux Mint将其用作操作系统保存点。
如果我使用，locate anaconda activate.sh我可能会得到：

只有前三个结果是相关的，那么如何排除目录？
答案1
使用 grep 手动排除目录
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/"
这将仅打印不包含字符串的路径/timeshift/
永久排除目录
由于时间移位目录的问题经常重复出现，您可能希望将其从所有定位查询中永久排除。
根据updatedb文档，您可以在 中/timeshift添加。运行后，所有查询现在都应排除该目录。PRUNEPATHS=/etc/updatedb.confupdatedbplocate/timeshift
