Strange character appear when running .bat file

I wrote a simple .bat file to get information from `ipconfig`, `ping` and `tracert` commands, When I run, the console showup some "1" characters that doesn't exist in my file.

Here is code in my file ``` ipconfig /all > klavis.txt ping chatwork.com > klavis.txt ping dock.streamedup.com > klavis.txt ping dock-staging.streamedup.com > klavis.txt tracert chatwork.com > klavis.txt tracert dock.streamedup.com > klavis.txt tracert dock-staging.streamedup.com > klavis.txt tracetcp chatwork.com > klavis.txt tracetcp dock.streamedup.com > klavis.txt tracetcp dock-staging.streamedup.com ```

and here is what console give me ``` Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Users\longnx\Downloads\ngnx>klavis.bat

C:\Users\longnx\Downloads\ngnx>ipconfig /all 1>klavis.txt

C:\Users\longnx\Downloads\ngnx>ping chatwork.com 1>klavis.txt

C:\Users\longnx\Downloads\ngnx>ping dock.streamedup.com 1>klavis.txt

C:\Users\longnx\Downloads\ngnx>ping dock-staging.streamedup.com 1>klavis.txt

C:\Users\longnx\Downloads\ngnx>tracert chatwork.com 1>klavis.txt

C:\Users\longnx\Downloads\ngnx>tracert dock.streamedup.com 1>klavis.txt

```

As you can see, there a `1` character next to `>` character.

What's wrong? and how could I fix it?

I run these commands on `Windows 7 Enterprise 64bit EN` if needed.

Solution:

I've made 2 mistakes

1. I don't know about `1` is STDIN, the `cmd` is too kind for me when it show up the `1` 2. I make a mistake between `>` and `>>`
