如果你有coreutils-7 (Ubuntu Karmic，而不是Jaunty)，那么你的排序命令应该有一个-V选项(版本排序)，你可以使用它来进行比较:

verlte() {
    [  "$1" = "`echo -e "$1\n$2" | sort -V | head -n1`" ]
}

verlt() {
    [ "$1" = "$2" ] && return 1 || verlte $1 $2
}

verlte 2.5.7 2.5.6 && echo "yes" || echo "no" # no
verlt 2.4.10 2.4.9 && echo "yes" || echo "no" # no
verlt 2.4.8 2.4.10 && echo "yes" || echo "no" # yes
verlte 2.5.6 2.5.6 && echo "yes" || echo "no" # yes
verlt 2.5.6 2.5.6 && echo "yes" || echo "no" # no

function version { echo "$@" | awk -F. '{ printf("%d%03d%03d%03d\n", $1,$2,$3,$4); }'; }

这样用:

if [ $(version $VAR) -ge $(version "6.2.0") ]; then
    echo "Version is up to date"
fi

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>。

这个怎么样?似乎有用?

checkVersion() {
subVer1=$1
subVer2=$2

[ "$subVer1" == "$subVer2" ] && echo "Version is same"
echo "Version 1 is $subVer1"
testVer1=$subVer1
echo "Test version 1 is $testVer1"
x=0
while [[ $testVer1 != "" ]]
do
  ((x++))
  testVer1=`echo $subVer1|cut -d "." -f $x`
  echo "testVer1 now is $testVer1"
  testVer2=`echo $subVer2|cut -d "." -f $x`
  echo "testVer2 now is $testVer2"
  if [[ $testVer1 -gt $testVer2 ]]
  then
    echo "$ver1 is greater than $ver2"
    break
  elif [[ "$testVer2" -gt "$testVer1" ]]
  then
    echo "$ver2 is greater than $ver1"
    break
  fi
  echo "This is the sub verion for first value $testVer1"
  echo "This is the sub verion for second value $testVer2"
done
}

ver1=$1
ver2=$2
checkVersion "$ver1" "$ver2"

GNU排序有一个选项:

printf '2.4.5\n2.8\n2.4.5.1\n' | sort -V

给:

2.4.5
2.4.5.1
2.8

### 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。
