#### fs.chown(path, uid, gid, callback)<a name="chown"></a>
Changes the owner and group of a file. Asynchronous [chown(2)](http://pubs.opengroup.org/onlinepubs/009695399/functions/chown.html). Callback gets no additional arguments. Both `uid` (user id) and `gid` (group id) arguments should be a JavaScript Number. By default, `0x0` is used (i.e., `root:root` ownership).
Example:
```javascript
fs.chown('/myfile.txt', 500, 500, function(err) {
if(err) throw err;
// /myfile.txt is now owned by user with id 500, group 500
});
```
#### fs.fchown(fd, uid, gid, callback)<a name="fchown"></a>
Changes the owner and group of a file. Asynchronous [chown(2)](http://pubs.opengroup.org/onlinepubs/009695399/functions/chown.html). Callback gets no additional arguments. Both `uid` (user id) and `gid` (group id) arguments should be a JavaScript Number. By default, `0x0` is used (i.e., `root:root` ownership).
Example:
```javascript
fs.open('/myfile.txt', function(err, fd) {
if(err) throw err;
fs.fchown(fd, 500, 500, function(err) {
if(err) throw err;
// /myfile.txt is now owned by user with id 500, group 500
fs.close(fd);
});
});
```
#### fs.chmod(path, mode, callback)<a name="chmod"></a>
Changes the mode of a file. Asynchronous [chmod(2)](http://pubs.opengroup.org/onlinepubs/009695399/functions/chmod.html). Callback gets no additional arguments. The `mode` argument should be a JavaScript Number, which combines file type and permission information. Here are a list of common values useful for setting the `mode`:
* File type `S_IFREG=0x8000`
* Dir type `S_IFDIR=0x4000`
* Link type `S_IFLNK=0xA000`
* Permissions `755=0x1ED`
* Permissions `644=0x1A4`
* Permissions `777=0x1FF`
* Permissions `666=0x1B6`
By default, directories use `(0x4000 | 0x1ED)` and files use `(0x8000 | 0x1A4)`.
Example:
```javascript
// S_IFREG | 0o777
var mode = 0x8000 | 0x1FF
fs.chmod('/myfile.txt', mode, function(err) {
if(err) throw err;
// /myfile.txt is a regular file with permissions 777
});
```
#### fs.fchmod(fd, mode, callback)<a name="fchmod"></a>
Changes the mode of a file. Asynchronous [chmod(2)](http://pubs.opengroup.org/onlinepubs/009695399/functions/chmod.html). Callback gets no additional arguments. The `mode` argument should be a JavaScript Number, which combines file type and permission information. By default, `755` (dir) and `644` (file) are used.
Example:
```javascript
fs.open('/myfile.txt', function(err, fd) {
if(err) throw err;
// S_IFREG | 0o777
var mode = 0x8000 | 0x1FF
fs.fchmod(fd, mode, function(err) {
if(err) throw err;
// /myfile.txt is a regular file with permissions 777
fs.close(fd);
});
});

Get the listing of a directory, returning an array of directory entries
in the following form:
```
{
path: <String> the basename of the directory entry
links: <Number> the number of links to the entry
size: <Number> the size in bytes of the entry
modified: <Number> the last modified date/time
type: <String> the type of the entry
contents: <Array> an optional array of child entries, if this entry is itself a directory
}
```
in the same form as [fs.stat()](#stat), with the exception that a new Array named
`contents` is added for directory entries, containing child entries.
By default `sh.ls()` gives a shallow listing. If you want to follow
directories as they are encountered, use the `recursive=true` option. NOTE:
