从 URL、HTML 或 JSON 中提取 Confluence 版本
Extract Confluence version from URL, HTML, or JSON
我正在尝试从 URL 等
中提取 版本
https://my.atlassian.com/download/feeds/current/confluence.json
这是我的 bash 脚本：
#!/bin/bash
# Get the actual version
url="https://de.atlassian.com/software/confluence/download"
actual_version="$(curl -s $url | grep -Po '(?<=version :)\d+' | head -1)"
echo $actual_version
不幸的是，它不只给我版本号。
知道如何以正确的方式做到这一点吗？
注意：问题根据评论进行了多项改进/修订。
TL;DR
这是从他们的 JSON 页面中提取版本的最终命令：
curl -s "https://my.atlassian.com/download/feeds/current/confluence.json" | grep -Po '(?<="version":")[^"]*' | head -1
6.11.0
