Ubuntu20.04 个人配置和i3美化

本文是基于个人习惯和审美，快速配置一个新ubuntu的步骤。脚本在资源里给出，但仍有部分配置文件需在脚本执行后手动修改,文中已用红色字体标出

更新apt源

1. 备份原来的源
2. 更换阿里源

# 备份
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
# 阿里源
sudo echo "deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
" > /etc/apt/sources.list

更新apt

sudo apt update
sudo apt upgrade -y

这个时间比较长

安装vim

sudo apt install -y vim

安装mysql8.0

sudo apt install -y mysql-client-8.0

安装jdk8

sudo apt install -y openjdk-8-jdk

安装git

sudo apt install -y git

安装python3,python

sudo apt install -y python3
sudo apt install -y python

安装typora

sudo snap install typora

安装搜狗输入法

访问搜狗输入法 for linux并下载自己需要的版本（一般都是X86-64）

下载完成后得到一个deb包,双击他安装或者按如下命令安装（deb包名字可能不一样）

cd ~/Downloads/
sudo dpkg -i sogoupinyin_2.1.0.0082_amd64.deb

安装网页的提示操作即可

安装VSCode

sudo snap install code --classics

终端美化-安装zsh,oh-my-zsh

sudo apt install -y zsh
cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
chsh -s /bin/zsh
cd ~/.oh-my-zsh/plugins/
git clone https://github.com/zsh-users/zsh-autosuggestions
git clone https://github.com/wting/autojump.git ~/.oh-my-zsh/plugins/autojump
cd autojump
./install.py

autojump使用:在终端输入 j a，或者jump a，会自动进入与a最匹配的你最可能想要进的最近进入过的目录

zsh-autosuggestions使用:在终端输入命令时，可以看到灰色的自动补全语句，按up down键可切换，,键可直接自动补全

需手动修改配置文件,打开~/.zshrc,找到ZSH_THEME="robbyrussell"，修改为ZSH_THEME="ys"

找到plugins,修改为

plugins=(gitzsh-autosuggestionsautojumpextractvi-modewd
)

在末尾加上[[ -s ~/.autojump/etc/profile.d/autojump.sh ]] && . ~/.autojump/etc/profile.d/autojump.sh

或者可以直接把下面我的.zshrc内容来替换你的.zshrc,内容有多但没有错

美化-安装终端仿真器tilix

下面那条命令用来替换默认终端

sudo apt install -y tilix
gsettings set org.gnome.desktop.default-applications.terminal exec 'tilix'

需手动配置

打开tilix后右键上面的那一栏找到preference，在appearance里找到Theme variant，设置为dark,同在这里找到Window style,设置为Disable CSD,hide toolbar

快速打开软件-rofi

sudo apt install -y rofi

终端中使用:rofi -show run

图片查看feh

sudo apt install -y feh

使用以下命令可以设置随机桌面图片

feh --randomize --bg-fill ~/picture # 后面为你放图片的路径,每运行一次随机替换一次

安装i3wm

sudo apt install -y i3
sudo apt install -y i3lock
sudo add-apt-repository ppa:regolith-linux/stable
sudo apt-get update
sudo apt-get install i3-gaps

重启后在登录前的右下角选择i3，进入后一路enter键,之后请找网络资源进行学习使用和配置，学好后可以不使用鼠标。

配置文件在~/.config/i3/config,以下为我的config

# This file has been auto-generated by i3-config-wizard(1).
# It will not be overwritten, so edit it as you like.
#
# Should you change your keyboard layout some time, delete
# this file and re-run i3-config-wizard(1).
## i3 config file (v4)
#
# Please see https://i3wm.org/docs/userguide.html for a complete reference!set $mod Mod4# Font for window titles. Will also be used by the bar unless a different font
# is used in the bar {} block below.
font pango:monospace 8# This font is widely installed, provides lots of unicode glyphs, right-to-left
# text rendering and scalability on retina/hidpi displays (thanks to pango).
#font pango:DejaVu Sans Mono 8# Before i3 v4.8, we used to recommend this one as the default:
# font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
# The font above is very space-efficient, that is, it looks good, sharp and
# clear in small sizes. However, its unicode glyph coverage is limited, the old
# X core fonts rendering does not support right-to-left and this being a bitmap
# font, it doesn’t scale on retina/hidpi displays.# Use Mouse+$mod to drag floating windows to their wanted position
