# Tools
Something about scripts
# Linux reinstall useage
## Features:
- "InstallNET.sh" will give you a clean, safe, official Linux system, and help you escape of your server providers' monitoring.
- The operation is easy, several minutes installation will be complated.
- Support Debian 8+, Ubuntu 14.04+, CentOS 6.
- Support major cloud providers, especially support Oracle Cloud ARM machine.
- You can modify architecture, mirror, firmware, ssh port, password etc. 
- Friendly to low memory machine(recommend RAM above 256MB), <b>If your machine RAM is less than 768MB, before Debian 11 and above version installation, you may should not bash it with "-firmware" or "-firmware --cdimage" parameters because it won't let machine installation go into low memory mode and causes installation failed!</b>
- Ubuntu 22.04 has cancelled net boot start features, so this program don't support Ubuntu 22.04 and above reinstallation(source: https://www.reddit.com/r/Ubuntu/comments/uroape/is_there_a_netbootiso_equivalent_for_2204_jammy/).
- South Korea debian official mirror(http://ftp.kr.debian.org/debian/) is usually crashed down, so I change mirror of Kyoto University to replace it. Japan debian mirror is from https://www.riken.jp/, a science research organization in Japan. America debian mirror is from Massachusetts Institute of Technology: https://web.mit.edu/.
- Completely  modified debian, such as support terminal files colorful displaying, permanently change dns server, disable expired certificates, add on a cute welcome introduction, pre-install many complements in preseeding progress, now enjoy a newly, comfortable, graceful debian experience!

to make changes validating!

# GroupPolicy import and export
This ".bat" script can only run in Windows. Although only one group-policy rule in Windows can be exported at a time and not support a global one and also have no GUI entrance to import another backuped group policy which exported from another computer. It can help you import or export GroupPolicy conveniently.
## Attentions
<ul>
<li>Compatible with all versions of Windows.</li>
<li>Only support the group-policy rules which exported by this script.</li>
<li>If you want to export group-policy rules. Folder which included group-policy files corresponds to current OS version strictly. Not support export rules which is different from current OS version.</li>
<li>Export operation is irreversible, be cautious to run it！</li>
<li>I provided a suggested rules file about Windows Server 2016.</li>
<li>You should run it on desktop.</li>
</ul>
