## Benchmark
A search in my home folder with ~80.000 subdirectories
and ~350.000 files. The `--hidden` for `fd` is needed
for a fair comparison, as *find* does this by default:
A search in my home folder with ~150.000 subdirectories and ~1M files. The given options for
`fd` are needed for a fair comparison (otherwise `fd` is even faster by a factor of 4 because it
does not have to search hidden and ignored paths):
``` bash
> time fd --hidden '\.jpg$' > /dev/null
0,39s user 0,40s system 99% cpu 0,790 total
> time fd --hidden --no-ignore --full-path '.*[0-9]\.jpg$' > /dev/null
1,03s user 0,92s system 99% cpu 1,961 total
> time find -iname '*.jpg' > /dev/null
0,36s user 0,42s system 98% cpu 0,789 total
```
Both tools found the exact same 5504 files and have
a comparable performance (averaged over multiple runs),
even though *fd* performs a regex search.
If we do the same for *find*, it is significantly slower:
``` bash
> time find -iregex '.*\.jpg$' > /dev/null
1,29s user 0,41s system 99% cpu 1,705 total
> time find -iregex '.*[0-9]\.jpg$' > /dev/null
3,98s user 0,84s system 99% cpu 4,832 total
```
Both tools found the exact same 14030 files and the results are comparable when averaged over
multiple runs.
## Install
With [cargo](https://github.com/rust-lang/cargo), you can clone, build and install *fd* with a single command:
