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

# Compare two versions.

#
# - operator:

#   + ``lesser_than``, ``-lt``, ``<``
#   + ``lesser_than_or_equal``, ``-le``, ``<=``
#   + ``greater_than``, ``-gt``, ``>``

#   + ``equal``, ``-eq``, ``==``
#   + ``not_equal``, ``-ne``, ``!=``

#
# **Version Format:** ``[0-9]+($VERSION_SEPARATOR[0-9]+)*`` (i.e. 1, 1.0, 90, 1.2.3.4)

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

这里有一个支持修订的纯Bash解决方案(例如。“1.0-r1”)，答案是基于丹尼斯·威廉姆森(Dennis Williamson)发布的答案。可以很容易地修改它以支持'-RC1'之类的东西，或者通过更改正则表达式从更复杂的字符串中提取版本。

有关实现的详细信息，请参考代码内注释和/或启用包含的调试代码:

与其编写冗长的代码使您的生活过于复杂，不如使用一些已经存在的东西。很多时候，当bash不够用时，python可以提供帮助。你仍然可以很容易地从bash脚本调用它(额外的好处:从bash到python的变量替换):

VERSION1=1.2.3
VERSION2=1.2.4

cat <<EOF | python3 | grep -q True
from packaging import version
print(version.parse("$VERSION1") > version.parse("$VERSION2"))
EOF

if [ "$?" == 0 ];  then
   echo "$VERSION1 is greater than $VERSION2"
else
   echo "$VERSION2 is greater or equal than $VERSION1"
fi

这里有更多信息:如何比较Python中的版本号?

ver_cmp()
{
    local IFS=.
    local V1=($1) V2=($2) I
    for ((I=0 ; I<${#V1[*]} || I<${#V2[*]} ; I++)) ; do
        [[ ${V1[$I]:-0} -lt ${V2[$I]:-0} ]] && echo -1 && return
        [[ ${V1[$I]:-0} -gt ${V2[$I]:-0} ]] && echo 1 && return
    done
    echo 0
}

ver_eq()
{
    [[ $(ver_cmp "$1" "$2") -eq 0 ]]
}

ver_lt()

    [[ $(ver_cmp "$1" "$2") -eq -1 ]]
}

ver_gt()
{
    [[ $(ver_cmp "$1" "$2") -eq 1 ]]
}

ver_le()
{
    [[ ! $(ver_cmp "$1" "$2") -eq 1 ]]
}

ver_ge()
{
    [[ ! $(ver_cmp "$1" "$2") -eq -1 ]]
}

测试:

( ( while read V1 V2 ; do echo $V1 $(ver_cmp $V1 $V2) $V2 ; done ) <<EOF

3.1    =  3.1.0


ver_lt 10.1.2 10.1.20 && echo 'Your version is too old'

Your version is too old

### 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。
