如何清除 Ubuntu 中的 journal、VScode 和 pip 缓存 ​

1. 清理 journal 缓存 ​

清除缓存和日志

(base) user@ubuntu:~$ journalctl --disk-usage 
Archived and active journals take up 2.2G in the file system.

(base) user@ubuntu:~$ cd /var/log/journal/
(base) user@ubuntu:~$ sudo rm -rf fa1bd666c72b41db99ad421752842c3f/
(base) user@ubuntu:~$ journalctl --disk-usage 
Archived and active journals take up 2.2G in the file system.

(base) user@ubuntu:~$ cd /var/log/journal/
(base) user@ubuntu:~$ sudo rm -rf fa1bd666c72b41db99ad421752842c3f/

以下三个命令主要清理升级缓存以及无用包

sudo apt-get autoclean                # 删除旧版本软件缓存
sudo apt-get clean                    # 删除系统内所有软件缓存
sudo apt-get autoremove             # 删除系统不再使用的孤立软件
sudo apt-get autoclean                # 删除旧版本软件缓存
sudo apt-get clean                    # 删除系统内所有软件缓存
sudo apt-get autoremove             # 删除系统不再使用的孤立软件

2. 清理 VSCode 缓存 ​

workspaceStorage ​

切换到 VS code 的插件目录下

(base) user@ubuntu:~$ cd ~/.config/Code/User/workspaceStorage/
(base) user@ubuntu:~$ cd ~/.config/Code/User/workspaceStorage/

查看该插件目录及其文件的大小

(base) user@ubuntu:~/.config/Code/User$ du workspaceStorage/ -h
(base) user@ubuntu:~/.config/Code/User/workspaceStorage$ du -h
(base) user@ubuntu:~/.config/Code/User$ du workspaceStorage/ -h
(base) user@ubuntu:~/.config/Code/User/workspaceStorage$ du -h

删除当前目录下的所有文件及目录

(base) user@ubuntu:~/.config/Code/User/workspaceStorage$ rm -rf *
(base) user@ubuntu:~/.config/Code/User/workspaceStorage$ rm -rf *

一篇不错的环境配置教程：Ubuntu20.04 下安装 VSCode（配置 C/C++ 开发环境）

ms-vscode.cpptools ​

根据这篇 discussions 的提示，我尝试清理了 VSCode 的缓存，发现并没有影响 VScode 的使用。

shell
cd ~/.cache/ && du vscode-cpptools/ -h     # 查看vscode-cpptools 目录大小
cd vscode-cpptools/ && rm -rf *            # 删除vscode-cpptools 目录下所有文件及目录
cd .. && du vscode-cpptools/ -h            # 验证vscode-cpptools 目录大小
cd ~/.cache/ && du vscode-cpptools/ -h     # 查看vscode-cpptools 目录大小
cd vscode-cpptools/ && rm -rf *            # 删除vscode-cpptools 目录下所有文件及目录
cd .. && du vscode-cpptools/ -h            # 验证vscode-cpptools 目录大小

cpp-tools

.cache

3. 清理 pip 缓存 ​

清除 pip cache

shell
ruoxi@ruoxi:~$ pip cache purge
ERROR: pip cache commands can not function since cache is disabled.   # 显示该功能已关闭

ruoxi@ruoxi:~$ pip config set global.cache-dir false                  # 使用pip命令关闭cache dir

cache-dir = false      # 新添加的命令，可以正常使用

ruoxi@ruoxi:~$ pip cache purg

ruoxi@ruoxi:~$ pip cache purg

再次验证，已关闭 pip cache 存储，成功
