对 flatpak 命令应用 hook

创建或编辑以下文件：

1
sudo nano /usr/local/bin/flatpak

在文件中添加以下内容：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
/usr/bin/flatpak $@

for app in $(/usr/bin/flatpak list --app --columns=application); do
    if ! [ -d ~/.var/app/"$app"/config/fontconfig ]; then
        mkdir -p ~/.var/app/"$app"/config/fontconfig
    fi
    if ! [ -f ~/.var/app/"$app"/config/fontconfig/fonts.conf ]; then
        cp /etc/fonts/local.conf ~/.var/app/"$app"/config/fontconfig/fonts.conf
        chmod 644 ~/.var/app/"$app"/config/fontconfig/fonts.conf
    elif ! diff -q /etc/fonts/local.conf ~/.var/app/"$app"/config/fontconfig/fonts.conf >/dev/null; then
        rm -rf ~/.var/app/"$app"/config/fontconfig/fonts.conf
        cp /etc/fonts/local.conf ~/.var/app/"$app"/config/fontconfig/fonts.conf
        chmod 644 ~/.var/app/"$app"/config/fontconfig/fonts.conf
    fi
done

保存并关闭文件后，赋予执行权限：

1
sudo chmod +x /usr/local/bin/flatpak

现在，每次使用 flatpak 命令安装或更新应用时，都会自动将字体配置文件复制到相应的应用配置目录中，从而确保字体设置的一致性。
