crudini用法
crudini --set [--existing] config_file section [param] [value]
crudini --get [--format=sh|ini] config_file [section] [param]
crudini --del [--existing] config_file section [param]
crudini --merge [--existing] config_file [section]
crudini 用于操作ini文件，可以设置、获取、删除、合并其中的变量
其中：config_file 代表要操作的文件名，section 表示变量所在的部分，如以下配置文件：
[DEFAULT] user = admin passwd = admin port = 8088 [URL] client = 127.0.0.1:8088 admin = 127.0.0.1:8080
section 则表示了以上配置文件中的DEFAULT 和 URL ，在命令中不需要加中括号[]，param 则如user ，passwd，client 等。
添加
$ crudini --set config_file section parameter value
更新
$ crudini --set [--existing] config_file section parameter value
删除
删除变量：
$ crudini --del config_file section parameter
删除section：
$ crudini --del config_file section
获取
$ crudini --del config_file section parameter
如果该标量不在某一个section里面，则section用一个空字符表示：
$ crudini --del config_file parameter
合并
将another.ini配置文件合并到config_file中：
$ crudini --merge config_file < another.ini
