 General Methods:
     h,  help            Show this manual
-    v,  version         Show version number
-
+    v,  version         Show version number\n
 IP Information Methods:
     pub,    public      Get Your Public IP Address
     priv,   private     Get Your Private IP Address
-    j,      json        Get Your Public IP's Full Information in Json
-
+    j,      json        Get Your Public IP's Full Information in Json\n
 Other methods can be also grabbed from json output,
     for example this is your json output:
-    \e[1;34m{
+    \033[34m{
         ...
-        "continent": "Europe",
-        "country": "Germany",
-        "region": "Bavaria",
-        "city": "Nuremberg",
-        "latitude": 49.4254092,
-        "longitude": 11.0796553,

+        \"longitude\": 11.0796553,
         ...
-    }\e[0m
+    }\033[0m
     and if you want to get IP's country:
-    \e[1;34m$ $filename country
-    Output: Germany\e[0m
