+> `iofs` is a bash-like module for reading and writing files on Node.js. It base on Node.js's native `fs` module.
+
+## property
+
+### self
+> It return the native `fs` module for more requests.
+
+
+

+> Just like bash's cat, it will read a file and return a Buffer.
+
+
+
+### ls(path)
+- path `<String>`
+
+> List all files and folders of the path given exclude '.' and '..'. I t return an array.
+
+
+### echo(data, file[, append][, encode])
+- data `<String>` | `<Buffer>` | `<Number>`
+- file `<String>`
+- append `<Boolean>` optional
+- encode `<String>` optional
+
+> Write/Append data to a file. creating the file if it does not yet exist.
+> If `append` is set true, it will append data to the file.
+> Default `encode` is utf8.
+
+```javascript
+let fs = require('iofs')
+
+fs.echo('hello ', 'test.txt') // replacing test.txt if it exists.
+
+fs.echo('world', 'test.txt', true) // append the data to test.txt
+
+```
+
+
+
+
+### chmod(file, mode)
+- file `<String>` | `<Buffer>`
+- mode `<Integer>`
+
+> Changes the mode of the file specified whose pathname is given.
+
+```javascript
+
+fs.chmod('test.txt', 777) // replacing test.txt if it exists.
+
+```

+
+### mv(from, to)
+- from `<String>`
+- to `<String>`
+
+> Move a fil to the target location. It can also use to renaming a file.
+
+
+
+### cp(from, to)
+- from `<String>`
+- to `<String>`
+
+> Copy a fil to the target location.
+
+
+
+### rm(path, recursion)
+- path `<String>`
+- recursion `<Boolean>`
+
+> Delete a file or a folder. If path is a folder, `recursion` must be set to true.
+
+```javascript
+
+fs.rm('./foo/test.txt')
+
+fs.rm('./foo', true)
+
+```
+
+
+
+### stat(path)
+- path `<String>`
+
+> Returns an instance of fs.Stats.
+
+
+### isdir(path)
+- path `<String>`
+
+> Return true if the path is a folder, and false when it is a file or not yet exists.
+
+
+
+### mkdir(path)
+- path `<String>`
+
+> Build a folder in where you want.
+
+
+
