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

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

如果它只是想知道一个版本是否比另一个版本低，我会检查sort——version-sort是否会改变我的版本字符串的顺序:

    string="$1
$2"
    [ "$string" == "$(sort --version-sort <<< "$string")" ]

下面是另一个纯bash版本，比公认的答案要小得多。它只检查版本是否小于或等于“最小版本”，并且它将按字典顺序检查字母数字序列，这通常会给出错误的结果(举个常见的例子，“snapshot”不晚于“release”)。它将工作的主要/次要。

is_number() {
    case "$BASH_VERSION" in
        3.1.*)
            PATTERN='\^\[0-9\]+\$'
            ;;
        *)
            PATTERN='^[0-9]+$'
            ;;
    esac

    [[ "$1" =~ $PATTERN ]]
}

min_version() {
    if [[ $# != 2 ]]
    then
        echo "Usage: min_version current minimum"
        return
    fi

    A="${1%%.*}"
    B="${2%%.*}"

    if [[ "$A" != "$1" && "$B" != "$2" && "$A" == "$B" ]]
    then
        min_version "${1#*.}" "${2#*.}"
    else
        if is_number "$A" && is_number "$B"
        then
            [[ "$A" -ge "$B" ]]
        else
            [[ ! "$A" < "$B" ]]
        fi

这在版本中最多为4个字段。
