@ -24,14 +24,14 @@ A command-line benchmarking tool (*inspired by [bench](https://github.com/Gabrie
To run a benchmark, you can simply call `hyperfine <command>...`. The argument(s) can be any
shell command. For example:
``` bash
> hyperfine 'sleep 0.3'
hyperfine 'sleep 0.3'
```
Hyperfine will automatically determine the number of runs to perform for each command. By default,
it will perform *at least* 10 benchmarking runs. To change this, you can use the `-m`/`--min-runs`
option:
``` bash
> hyperfine --min-runs 5 'sleep 0.2' 'sleep 3.2'
hyperfine --min-runs 5 'sleep 0.2' 'sleep 3.2'
```

If you want to run the benchmark on a warm cache, you can use the `-w`/`--warmup` option to perform
a certain number of program executions before the actual benchmark:
``` bash
> hyperfine --warmup 3 'grep -R TODO *'
hyperfine --warmup 3 'grep -R TODO *'
```
Conversely, if you want to run the benchmark for a cold cache, you can use the `-p`/`--prepare`
