iso-m

#!/bin/sh
# 本脚本用于管理 openSUSE Tumbleweed ISO 文件。
#
# 主要功能有：
# 1. 下载 DVD/Live ISO 文件、sha256 文件和 asc 证书文件
# 2. 校验新旧 ISO 文件（计算哈希，验证 GPG 签名）
# 3. 更新替换旧版 ISO 文件
#
# 注意：
# 1. 使用前请完整阅读一遍脚本，使用时风险自负。
# 2. 用户需要自行修改需要修改的变量。
# 3. 用户需要自己配置 gpg 工具。

配置文件

git

在 ~/.gitconfig 中，写入：

[user]
    name = Poplar at twilight
    email = poplar.cubic@gmail.com
[http]
    proxy = http://127.0.0.1:7890

proxychains-ng

/etc/proxychains.conf：

quiet_mode
http 127.0.0.1 7890

python

设置代理（~/.config/pip/pip.conf）：

[global]
proxy=http://localhost:7890

nano

如果 nano 编辑器没有语法高亮，则创建如下文件：

• ~/.nanorc

include /usr/share/nano/*.nanorc

bashrc
