Exploration on Ubuntu

Basic Operations For A New Ubuntu System

Preliminary

安装与卸载

wsl --list
wsl --unregister Ubuntu

更改密码

sudo passwd update
su

添加代理

1. cat /etc/resolv.conf查看IP地址，记作yourip
2. 查看代理窗口（如Clash客户端界面），记作yourport
3. 进入WSL Ubuntu，执行export ALL_PROXY="http://yourip:yourport"
4. 当主机ip发生变化时需重新设置

换源

需要保证源的正确性：

1. 通过lsb_release -a查看Ubuntu版本
2. 参考网址：sunanli 复制源，更改/etc/apt/sources.list文件
3. sudo apt-get update

安装软件

1. sudo apt install vim
2. sudo apt install build-essential
3. sudo apt install valgrind

更改文件/目录权限

• chown命令，详见wuling129

wsl与windows文件相互访问

• wsl访问windows文件：/mnt/目录下即为windows磁盘
• windows访问wsl文件：文件管理器左侧显示的Linux即为wsl

Git 操作

设置用户信息

git config --global user.name ""
git config --global user.email ""

查看用户信息

git config user.name
git config user.email

设置记住密码

git config credential.helper store

常见操作

git clone xxx
git add/reset xxx
git commit -m ""
git push
git config --global --unset http.proxy git config --global --unset https.proxy

Vim 操作

sudo apt-get install vim

.vimrc配置文件

1. vim ~/.vimrc open the config file
2. install Vundle and use it to install plugs you’d like to use.
   1. git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
   2. edit your .vimrc file and put your plug installation statement between call vundle#begin() and call vundle#end(). Just do it as follows:

       call vundle#begin()
       " default installation
       Plugin 'VundleVim/Vundle.vim'
       " install doxygen for better comments, usage like, :Dox, :DoxAuthor
       Plugin 'vim-scripts/DoxygenToolkit.vim'
       " install Chinese vim document, usage like, :help
       Plugin 'asins/vimcdoc'
       call vundle#end()
      

      then, save the file and use :PluginInstall to start installation.
