假设我已xarchiver默认安装，并默认与大多数存档类型关联。
我已经安装了engrampa，现在想将其与各种存档类型相关联。我不想单独更改每个 MIME 关联。
当我卸载时xarchiver，各种存档类型的关联自动更改为engrampa.
有没有办法在不卸载的情况下做到这一点xarchiver？类似于“将应用程序 X 与其支持的所有 MIME 类型相关联”？
如果重要的话，我正在使用 Fedora 38 XFCE spin。

输出：
cat engrampa.desktop | grep "MimeType" | cut -d"=" -f2 | tr ";" "\n" | xargs -n1 printf "xdg-mime default engrampa.desktop %s; \\ \n"
该文件engrampa.desktop应该位于
~/.local/share/applications

如果找不到它使用find命令
