# 自动清理老旧的包缓存
|
|
|
|
|
|
|
|
|
|
|
|
建立一个 hook 文件在 `/etc/pacman.d/hooks/clean_package_cache.hook`，内容如下：
|
|
|
|
|
|
|
|
|
|
|
|
``` conf
|
|
|
|
|
|
[Trigger]
|
|
|
|
|
|
Operation = Upgrade
|
|
|
|
|
|
Operation = Install
|
|
|
|
|
|
Operation = Remove
|
|
|
|
|
|
Type = Package
|
|
|
|
|
|
Target = *
|
|
|
|
|
|
[Action]
|
|
|
|
|
|
Description = Cleaning pacman cache...
|
|
|
|
|
|
When = PostTransaction
|
|
|
|
|
|
Exec = /usr/bin/paccache -rk3
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
系统会在每次安装升级卸载以后执行 `/usr/bin/paccache -rk3` 删除包的历史缓存，仅保留最近的3个版本。
