以下是我的剧本：

#!/bin/bash
if [ "$EUID" -ne 0 ]; then echo "Run as root." 1>&2; exit 1; fi
if [ "$#" -lt 1 ]; then echo "Usage: $0 <i/u> <AppImage_Name>" 1>&2; exit 1; fi
op="$1"; img="$2"
basename_no_ext=$(basename ${img%.*})

case "$op" in
  i|install)
    mv "$img" "/usr/local/bin/" && chmod +x "/usr/local/bin/$img" && ln -s "/usr/local/bin/$img" "/usr/local/bin/${img%.*}"
    if [ $? -eq 0 ]; then
      echo "Installed. Run $basename_no_ext."
    else
      echo "Installation failed." 1>&2
    fi
    ;;
  u|uninstall)
    rm -f "/usr/local/bin/$img" "/usr/local/bin/${img%.*}"
    if [ $? -eq 0 ]; then
      echo "Uninstalled."
    else
      echo "Uninstallation failed." 1>&2
    fi
    ;;
  *)
    echo "Invalid. Use 'i/u' or 'install/uninstall'." 1>&2
    exit 1
    ;;
esac

要安装它：将上述文本复制到名为“www.example.com“的本地文件中install-app.sh，然后在同一文件夹中执行：
sudo ./install-app.sh i ./install-app.sh
然后，要使用它，运行：
sudo install-app i ./nvim.appimage
要卸载，请运行：
sudo install-app u nvim
请随意改进或分享此代码。
