通用bash脚本安装apt-get和yum

我想写一个简单的bash包装，其摘要yum和apt-get。基本上，所以我们可以做这样的事情universal-install curl这是我到目前为止有：通用bash脚本安装apt-get和yum

# universal-install 
package=$1 
apt=`command -v apt-get` 
yum=`command -v yum` 

if [ -n "$apt" ]; then 
    apt-get update 
    apt-get -y install $package 
elif [ -n "$yum" ]; then 
    yum -y install $package 
else 
    echo "Err: no path to apt-get or yum" >&2; 
    exit 1; 
fi

是否有可以由任何错误或改进/优化？

潜在的问题是分布不同命名他们的所有软件包。 Debian'apt-get package'很可能不会与Redhat'yum install软件包具有相同的名称' –

Yah，让我们忽略软件包名称的差异。不是我可以自动处理的东西，我知道。如果有一个服务（api）为最常见的发行版返回了软件包名称，那真的很酷。 – Justin

如果你打算这样做，为什么要求用户告诉脚本使用哪个工具？

#!/bin/bash 
# Find our package manager 
if VERB="$(which apt-get)" 2> /dev/null; then 
    echo "Debian-based" 
elif VERB="$(which yum)" 2> /dev/null; then 
    echo "Modern Red Hat-based" 
elif VERB="$(which portage)" 2> /dev/null; then 
    echo "Gentoo-based" 
elif VERB="$(which pacman)" 2> /dev/null; then 
    echo "Arch-based" 
else 
    echo "I have no idea what I'm doing." >&2 
    exit 1 
fi 
if [[ 1 -ne $# ]]; then 
    echo "Syntax: $0 PACKAGE" 
    exit 1 
fi 
$VERB "$1" 
exit $?

稍好一点的去看/etc/issue看看你的发行版本是什么，并据此行事。

？他不要求用户告诉脚本中哪个地方使用哪个工具。也不要使用'which' – BroSlow

有哪些与我应该知道的'哪个'有什么不同？询问头脑想知道。 – DopeGhoti

是的，不要使用'which'来检查命令是否存在，这是为什么：http://stackoverflow.com/questions/592620/how-to-check-if-a-program-exists-from-a -bash-script – Justin

看看how pacapt detects the OS：

# Detect package type from /etc/issue 
_found_arch() { 
    local _ostype="$1" 
    shift 
    grep -qis "$*" /etc/issue && _OSTYPE="$_ostype" 
} 

# Detect package type 
_OSTYPE_detect() { 
    _found_arch PACMAN "Arch Linux" && return 
    _found_arch DPKG "Debian GNU/Linux" && return 
    _found_arch DPKG "Ubuntu" && return 
    _found_arch YUM "CentOS" && return 
    _found_arch YUM "Red Hat" && return 
    _found_arch YUM "Fedora" && return 
    _found_arch ZYPPER "SUSE" && return 

    [[ -z "$_OSTYPE" ]] || return 

    # See also https://github.com/icy/pacapt/pull/22 
    # Please not that $OSTYPE (which is `linux-gnu` on Linux system) 
    # is not our $_OSTYPE. The choice is not very good because 
    # a typo can just break the logic of the program. 
    if [[ "$OSTYPE" != "darwin"* ]]; then 
    _error "Can't detect OS type from /etc/issue. Running fallback method." 
    fi 
    [[ -x "/usr/bin/pacman" ]]   && _OSTYPE="PACMAN" && return 
    [[ -x "/usr/bin/apt-get" ]]   && _OSTYPE="DPKG" && return 
    [[ -x "/usr/bin/yum" ]]    && _OSTYPE="YUM" && return 
    [[ -x "/opt/local/bin/port" ]]  && _OSTYPE="MACPORTS" && return 
    command -v brew >/dev/null   && _OSTYPE="HOMEBREW" && return 
    [[ -x "/usr/bin/emerge" ]]   && _OSTYPE="PORTAGE" && return 
    [[ -x "/usr/bin/zypper" ]]   && _OSTYPE="ZYPPER" && return 
    if [[ -z "$_OSTYPE" ]]; then 
    _error "No supported package manager installed on system" 
    _error "(supported: apt, homebrew, pacman, portage, yum)" 
    exit 1 
    fi 
}

正如你可以看到它首先检查/etc/issue，则没有脚本查找每个包管理器相关的可执行文件。

但是，为什么不只是使用pacapt，而不是滚动自己的？

+1表示最后一行。结束了做到这一点，哈哈。 –

命令lsb_release你能帮忙吗？

我一直在寻找一个班轮安装一个软件包，但没有找到任何所以这是我的最终版本：

这是特定的unzip包，但可以改变apt-get/yum上可用的任何其他软件包。

希望这会帮助别人:)
