这也是一个纯bash解决方案，因为printf是bash内置的。

function ver()
# Description: use for comparisons of version strings.
# $1  : a version string of form 1.2.3.4
# use: (( $(ver 1.2.3.4) >= $(ver 1.2.3.3) )) && echo "yes" || echo "no"
{
    printf "%02d%02d%02d%02d" ${1//./ }
}

我实现了一个函数，返回与Dennis Williamson相同的结果，但使用更少的行数。它最初执行一个健全性检查，导致1..0从他的测试中失败(我认为应该是这样)，但他所有的其他测试都通过了这段代码:

#!/bin/bash
version_compare() {
    if [[ $1 =~ ^([0-9]+\.?)+$ && $2 =~ ^([0-9]+\.?)+$ ]]; then
        local l=(${1//./ }) r=(${2//./ }) s=${#l[@]}; [[ ${#r[@]} -gt ${#l[@]} ]] && s=${#r[@]}

        for i in $(seq 0 $((s - 1))); do
            [[ ${l[$i]} -gt ${r[$i]} ]] && return 1
            [[ ${l[$i]} -lt ${r[$i]} ]] && return 2
        done

        return 0
    else
        echo "Invalid version number given"
        exit 1
    fi
}

### the answer is does we second argument is higher
function _ver_higher {
        ver=`echo -ne "$1\n$2" |sort -Vr |head -n1`
        if [ "$2" == "$1" ]; then
                return 1
        elif [ "$2" == "$ver" ]; then
                return 0
        else
                return 1
        fi
}

if _ver_higher $1 $2; then
        echo higher
else
        echo same or less
fi

它非常简单和小。

可能没有普遍正确的方法来实现这一点。如果您正在尝试比较Debian包系统中的版本，请尝试dpkg——compare-versions <first> <relation> <second>。

我不喜欢这些解决方案，因为它们漏洞百出、不可移植等等。

我(目前)努力提出一个更好的解决方案……src: version_compare(),测试

    echo "Version is up to date"
