    Input:
      Files or directories, leave blank to use stdin

### Types

	css     text/css
	htm     text/html
	html    text/html
	js      application/javascript
	json    application/json
	svg     image/svg+xml
	xml     text/xml

## Examples
Minify **index.html** to **index-min.html**:
```sh
$ minify -o index-min.html index.html
```

Minify **index.html** to standard output (leave `-o` blank):
```sh
$ minify index.html
```

Normally the mimetype is inferred from the extension, to set the mimetype explicitly:
```sh
$ minify --type=html -o index-min.tpl index.tpl
```

You need to set the type or the mimetype option when using standard input:
```sh
$ minify --mime=application/javascript < script.js > script-min.js

$ cat script.js | minify --type=js > script-min.js
```

### Directories
You can also give directories as input, and these directories can be minified recursively.

Minify files in the current working directory to **out/** (no subdirectories):
```sh
$ minify -o out/ .
```

Minify files recursively in **src/**:
```sh
$ minify -r -o out/ src
```

Minify only javascript files in **src/**:
```sh
$ minify -r -o out/ --match=\.js src
```

### Concatenate
When multiple inputs are given and either standard output or a single output file, it will concatenate the files together.

Concatenate **one.css** and **two.css** into **style.css**:
```sh
$ minify -o style.css one.css two.css
```

Concatenate all files in **styles/** into **style.css**:
```sh
$ minify -o style.css styles
```

You can also use `cat` as standard input to concatenate files and use gzip for example:
```sh
$ cat one.css two.css three.css | minify --type=css | gzip -9 -c > style.css.gz
```

### Watching
To watch file changes and automatically re-minify you can use the `-w` or `--watch` option.

Minify **style.css** to itself and watch changes:
```sh
$ minify -w -o style.css style.css
```

Minify and concatenate **one.css** and **two.css** to **style.css** and watch changes:
```sh
$ minify -w -o style.css one.css two.css
```

Minify files in **src/** and subdirectories to **out/** and watch changes:
```sh
$ minify -w -r -o out/ src
```
