在本地而不是Docker中运行测试时，我也有类似的需求。基本上，我只想安装任何尚未安装的.deb文件。

# If there are .deb files in the folder, then install them
if [ `ls -1 *.deb 2> /dev/null | wc -l` -gt 0 ]; then
  for file in *.deb; do
    # Only install if not already installed (non-zero exit code)
    dpkg -I ${file} | grep Package: | sed -r 's/ Package:\s+(.*)/\1/g' | xargs dpkg -s
    if [ $? != 0 ]; then
        dpkg -i ${file}
    fi;
  done;
else
  err "No .deb files found in '$PWD'"
fi

我想我能看到的唯一问题是它没有检查包的版本号，所以如果.deb文件是一个更新的版本。这样就不会覆盖当前安装的包。

为了更明确一点，这里有一些Bash脚本，用于检查包并在需要时安装它。当然，您可以在发现包丢失时执行其他操作，例如简单地使用错误代码退出。

REQUIRED_PKG="some-package"
PKG_OK=$(dpkg-query -W --showformat='${Status}\n' $REQUIRED_PKG|grep "install ok installed")
echo Checking for $REQUIRED_PKG: $PKG_OK
if [ "" = "$PKG_OK" ]; then
  echo "No $REQUIRED_PKG. Setting up $REQUIRED_PKG."
  sudo apt-get --yes install $REQUIRED_PKG
fi

如果脚本在GUI中运行(例如，它是一个Nautilus脚本)，您可能想要用'gksudo'调用替换'sudo'调用。

这一行代码为“nano”包返回1(已安装)或0(未安装)…

$(dpkg-query -W -f='${Status}' nano 2>/dev/null | grep -c "ok installed")

即使包不存在或不可用。

下面的例子将安装'nano'包，如果它没有安装…

if [ $(dpkg-query -W -f='${Status}' nano 2>/dev/null | grep -c "ok installed") -eq 0 ];
then
  apt-get install nano;
fi

有点以你的为基础，只是更“优雅”一点。只是因为我很无聊。

#!/bin/bash
FOUND=("\033[38;5;10m")
NOTFOUND=("\033[38;5;9m")
PKG="${@:1}"
command ${PKG} &>/dev/null
if [[ $? != 0 ]]; then
    echo -e "${NOTFOUND}[!] ${PKG} not found [!]"
    echo -e "${NOTFOUND}[!] Would you like to install ${PKG} now ? [!]"
    read -p "[Y/N] >$ " ANSWER
    if [[ ${ANSWER} == [yY] || ${ANSWER} == [yY][eE][sS] ]]; then
        if grep -q "bian" /etc/os-release; then
            sudo apt-get install ${PKG}
        elif grep -q "arch" /etc/os-release; then
            if [[ -f /bin/yay ]] || [[ -f /bin/yaourt ]]; then
                yaourt -S ${PKG} 2>./err || yay -S ${PKG} 2>./err
            else
                sudo pacman -S ${PKG}
            fi
        elif grep -q "fedora" /etc/os-release; then
             sudo dnf install ${PKG}
        else
            echo -e "${NOTFOUND}[!] This script couldn't detect your package manager [!]"
            echo -e "${NOTFOUND}[!] Manually install it [!]"
        fi
    elif [[ ${ANSWER} == [nN] || ${ANSWER} == [nN][oO] ]]; then
        echo -e "${NOTFOUND}[!] Exiting [!]"
    fi
else
    echo -e "${FOUND}[+] ${PKG} found [+]"
fi

这个特性已经存在于Ubuntu和Debian的command-not-found包中。
