感谢Dennis的解决方案，我们可以扩展它以允许比较运算符'>'，'<'，'='，'=='，'<='和'>='。

# compver ver1 '=|==|>|<|>=|<=' ver2
compver() { 
    local op
    vercomp $1 $3
    case $? in
        0) op='=';;
        1) op='>';;
        2) op='<';;
    esac
    [[ $2 == *$op* ]] && return 0 || return 1
}

然后我们可以在表达式中使用比较运算符，比如:

compver 1.7 '<=' 1.8
compver 1.7 '==' 1.7
compver 1.7 '=' 1.7

并且只测试结果的真/假，比如:

if compver $ver1 '>' $ver2; then
    echo "Newer"
fi

您可以通过版本命令行查看版本约束

$ version ">=1.0, <2.0" "1.7"
$ go version | version ">=1.9"

Bash脚本示例:

#!/bin/bash

if `version -b ">=9.0.0" "$(gcc --version)"`; then
  echo "gcc version satisfies constraints >=9.0.0"
else
  echo "gcc version doesn't satisfies constraints >=9.0.0"
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。

我遇到并解决了这个问题，添加了一个额外的(更短更简单的)答案…

首先注意，扩展shell比较失败了，你可能已经知道了…

    if [[ 1.2.0 < 1.12.12 ]]; then echo true; else echo false; fi
    false

使用sort -t'。'-g(或者kanaka提到的sort -V)来排序版本和简单的bash字符串比较，我找到了一个解决方案。输入文件包含列3和列4中的版本，我想对它们进行比较。这将遍历列表，确定匹配项或其中一个大于另一个。希望这仍然可以帮助那些希望使用bash尽可能简单地做到这一点的人。

while read l
do
    #Field 3 contains version on left to compare (change -f3 to required column).
    kf=$(echo $l | cut -d ' ' -f3)
    #Field 4 contains version on right to compare (change -f4 to required column).
    mp=$(echo $l | cut -d ' ' -f4)

    echo 'kf = '$kf
    echo 'mp = '$mp

    #To compare versions m.m.m the two can be listed and sorted with a . separator and the greater version found.
    gv=$(echo -e $kf'\n'$mp | sort -t'.' -g | tail -n 1)

    if [ $kf = $mp ]; then 
        echo 'Match Found: '$l
    elif [ $kf = $gv ]; then
        echo 'Karaf feature file version is greater '$l
    elif [ $mp = $gv ]; then
        echo 'Maven pom file version is greater '$l
   else
       echo 'Comparison error '$l
   fi
done < features_and_pom_versions.tmp.txt

感谢Barry的博客给出了排序的想法…… 裁判:http://bkhome.org/blog/?viewDetailed=02199

下面是一个不需要任何外部工具的纯Bash版本:

        return 0
    fi
    local IFS=.
    local i ver1=($1) ver2=($2)
    # fill empty fields in ver1 with zeros
    for ((i=${#ver1[@]}; i<${#ver2[@]}; i++))
    do
        ver1[i]=0
    done
    for ((i=0; i<${#ver1[@]}; i++))
    do
        if [[ -z ${ver2[i]} ]]
        then
            # fill empty fields in ver2 with zeros
            ver2[i]=0
        fi
        if ((10#${ver1[i]} > 10#${ver2[i]}))
        then
            return 1
        fi
        if ((10#${ver1[i]} < 10#${ver2[i]}))

### Usage:

version_compare "1.2.3" "1.2.4"
# Output: <
