Dummyfile is a cli tool/package for creating a fixed-size dummy file with random contents.

## Usage

### Install as package

`go get -u github.com/liweiyi88/dummyfile/dummyfile`

Then use it in your code

```

import "github.com/liweiyi88/dummyfile/dummyfile"

func main() {

    file, err := os.Create(path)

    if err != nil {

        return fmt.Errorf("failed to create dummy file: %v", err)

    }

    defer func() {

        err := file.Close()

        if err != nil {

            log.Printf("failed to close file: %s", file.Name())

        }

    }()

    // as the Create method accepts the io.Writer.

    // you have the flexibility to test not only the file but any io.Writer.

    err := dummyfile.Create(file, 100*dummyfile.GB)

    //....

}

```

### Install as binary

`dummyfile` binaries are available in https://github.com/liweiyi88/dummyfile/releases. Use the latest version of the binary that is suitable to your OS.

After downloading the binary and move it to the folder that is in your $PATH env var (e.g. `/usr/local/bin/dummyfile`), give it executable permissions (e.g. `sudo chmod +x /usr/local/bin/dummyfile`). Then you should be able to run it:

```

$ dummyfile /path/to/dummy.txt --size 100gb

```
