This sounds like an awesome tool, and the "hacker spirit" of it really speaks to me.<p>It's really fitting to have a supremely technical and focused tool like this be described with things like "pretty C expressions" and (my favorite) "it's like find(1), but more fun to use", because obviously writing low-level C-like expressions to match against files is <i>fun</i>, most of all. Love it.<p>Also some of the examples are truly powerful, and at least I was not aware of any tool that could do things like this:<p><pre><code> # Find executable files that are larger than 10KiB, and have not been executed in the last 24 hours:
anyx && sz > 10K && atime < ago(day)
# Find regular files with multiple hard links
f && nlink > 1
# Find symlinks whose ultimate targets are on a different filesystem:
texists && tdev != dev
</code></pre>
Examples all cherry-picked from the manual page, and I picked the most terse version, more readable/explanatory versions using fewer built-ins are also available.<p>Many of the examples feel liks "I would never need that"-territory, until you do and then it's like impossible unless you write your own specialized tool to do it, or reach for this. Very cool!
