# debian技巧

## 添加 ll 命令

:::tip
由于 Debian 系统没有自带 `ll` 命令，且 `ls -al` 没有颜色显示。
:::

```shell
cat << EOF > /etc/profile.d/init_alias.sh
alias cp='cp -i' 2>/dev/null
alias egrep='egrep --color=auto' 2>/dev/null
alias fgrep='fgrep --color=auto' 2>/dev/null
alias grep='grep --color=auto' 2>/dev/null
alias l.='ls -d .* --color=auto' 2>/dev/null
alias ll='ls -l --color=auto' 2>/dev/null
alias ls='ls --color=auto' 2>/dev/null
alias mv='mv -i' 2>/dev/null
alias rm='rm -i' 2>/dev/null
alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde' 2>/dev/null
EOF
cat << EOF > /root/.vimrc
autocmd FileType * setlocal formatoptions-=c
set nocompatible
set backspace=indent,eol,start
EOF
```

## 默认编辑器修改

```bash
cat << EOF >> /root/.bashrc
export EDITOR=vim
EOF
```

## vim规范配置

```bash
cat << EOF > /etc/vim/vimrc.local
set tabstop=4
set shiftwidth=4
set softtabstop=4
set expandtab
let skip_defaults_vim = 1
if has('mouse')
set mouse-=a
endif

EOF
```

## apt 缓存代理

```bash
# 有网的机器
apt install -y apt-cacher-ng
# 没网apt 没网的机器
cat > /etc/apt/apt.conf.d/01proxy << 'EOF'
Acquire::http::Proxy "http://jumper:3142";
Acquire::https::Proxy "http://jumper:3142";
EOF
```
