// the root '/' now contains a directory 'test' containing the directory 'mkdirp' // the root '/' now contains a directory 'test' containing the directory 'mkdirp'
}); });
``` ```
#### sh.wget(url, [options], callback)<a name="wget"></a>
Downloads the file at `url` and saves it to the filesystem.
The file is saved to a file named with the filename portion of the url
unless the `options.filename` is present, in which case that
filename is used instead. The callback receives `(error, path)`,
where `path` is the full path to the downloaded file.
Example:
```javascript
// Download the file at /files/file.json
sh.wget('/files/file.json', function(err, path) {
if(err) throw err;
// /file-134134513 is now saved to the fs
});
// Download the file at /files/file.json, specifying a filename
sh.wget('/files/file.json', {filename: 'file.json'}, function(err, path) {
if(err) throw err;
// /file.json is now saved to the fs
});
```
#### sh.zip(zipfile, paths, [options], callback)]<a name="zip"></a>
Creates a zip archive named `zipfile` using the paths (files, dirs) listed in `paths`.
Valid options include `recursive=true`, which when set, causes directories to be followed
deeply. The `paths` argument must either be a single path (String) or a list of paths
(Array of String). The zip archive file, named in `zipfile`, must not exist or an error
will be returned on the callback. The callback receives `(error)`.
Examples:
```javascript
// Compress a single file
sh.zip('/data.zip', '/data.txt', function(err) {
if(err) throw err;
// /data.zip is now the compressed archive of /data.txt
});
// Compress multiple files
sh.zip('/data.zip', ['/data.txt', '/data2.txt'], function(err) {
if(err) throw err;
// /data.zip is now the compressed archive of /data.txt and /data2.txt
});
// Compress the entire filesystem, starting at the root /
sh.zip('/fs-backup.zip', '/', { recursive: true }, function(err) {
if(err) throw err;
// /fs-backup.zip now contains the entire filesystem
});
```
#### sh.unzip(zipfile, [options], callback)]<a name="zip"></a>
Extracts files and directories from a zip archive named `zipfile`. If `zipfile` does not
exist, an error is returned on the callback. Valid options include `destination`, which
is the path to use when extracting the files (defaults to the shell's current working directory).
If an optional `destination` path is specified, it must first exist. The callback receives `(error)`.
Examples:
```javascript
// Extract files in /backup.zip to the current directory
sh.unzip('/backup.zip', function(err) {
if(err) throw err;
// The current working directory now contains all files archived in backup.zip
});
// Extract files in /backup.zip to the /backup directory
sh.mkdirp('/backup', function(err) {
if(err) throw err;
sh.unzip('/backup.zip', { destination: '/backup' }, function(err) {
if(err) throw err;
// The current working directory now contains all files archived in backup.zip
});
});
