 ## Examples
 Start server on port 8080, root directory is current working  directory:
 ```sh
-server -l 8080
+ghfs -l 8080
 ``` 
 
 Start server on port 8080, root directory is /usr/share/doc:
 ```sh
-server -l 8080 -r /usr/share/doc
+ghfs -l 8080 -r /usr/share/doc
 ```
 
 Start server on default port, root directory is /tmp, and allow upload files to file system directory /tmp/data:
 ```sh
-server -r /tmp -u /data
+ghfs -r /tmp -u /data
 ```
 
 Share files from /etc, but also mount /usr/share/doc to url path /doc
 ```sh
-server -r /etc -a :/doc:/usr/share/doc
+ghfs -r /etc -a :/doc:/usr/share/doc
 ```
 
 Start server on port 8080, serve for HTTPS protocol
 ```sh
-server -k /path/to/certificate/key -c /path/to/certificate/file -l 8080
+ghfs -k /path/to/certificate/key -c /path/to/certificate/file -l 8080
 ```
 
 Do not show hidden unix directories and files that starts with `.`.
 Tips: wrap wildcard by quotes to prevent expanding by shell.
 ```sh
-server -H '.*'
+ghfs -H '.*'
 ```
 
 Show access log on console:
 ```sh
-server -L -
+ghfs -L -
 ```
 
 Http Basic Auth:
 - requires authentication for url /files
 - username: user1, password: pass1
 - username: user2, password: pass2
 ```sh
-server --auth /files --user user1:pass1 --user-sha1 user2:8be52126a6fde450a7162a3651d589bb51e9579d

 ## 举例
 在8080端口启动服务器，根目录为当前工作目录：
 ```sh
-server -l 8080
+ghfs -l 8080
 ``` 
 
 在8080端口启动服务器，根目录为 /usr/share/doc：
 ```sh
-server -l 8080 -r /usr/share/doc
+ghfs -l 8080 -r /usr/share/doc
 ```
 
 在默认端口启动服务器，根目录为/tmp，并允许上传文件到/tmp/data：
 ```sh
-server -r /tmp -u /data
+ghfs -r /tmp -u /data
 ```
 
 共享/etc下的文件，同时把/usr/share/doc挂载到URL路径/doc下：
 ```sh
-server -r /etc -a :/doc:/usr/share/doc
+ghfs -r /etc -a :/doc:/usr/share/doc
 ```
 
 在8080端口启动服务器，使用HTTPS协议：
 ```sh
-server -k /path/to/certificate/key -c /path/to/certificate/file -l 8080
+ghfs -k /path/to/certificate/key -c /path/to/certificate/file -l 8080
 ```
 
 不显示`.`开头的unix隐藏目录和文件。提示：用引号括起通配符以避免shell展开：
 ```sh
-server -H '.*'
+ghfs -H '.*'
 ```
 
 在命令行显示访问日志：
 ```sh
-server -L -
+ghfs -L -
 ```
 
 http基本验证：
 - 对URL /files 启用验证
 - 用户名：user1，密码：pass1
 - 用户名：user2，密码：pass2
 ```sh
-server --auth /files --user user1:pass1 --user-sha1 user2:8be52126a6fde450a7162a3651d589bb51e9579d
