从 URL 中提取 Google 驱动器文件夹 ID

Question

我只是想从一堆不同的 google 驱动器 URL 的

中提取 Google 驱动器文件夹 ID

cat links.txt

经过 trial/error 一个小时后，我确实想出了这个正则表达式 - ([01A-Z])(?=[\w-]*[A-Za-z])[\w-]+

除了无法正确处理倒数第 3 个 link 外，它似乎运行良好。如果 URL 中有多个嵌套文件夹 ID，我需要输出中最里面的一个。有人可以帮我解决这个错误并可能改进正则表达式，如果它可以比我的更有效的方式完成

Answer 1

你可以试试这个sed:

sed -E 's~.*[/=]([01A-Z][-_[:alnum:]]+)([?/].*|$)~~' links.txt

Answer 2

使用 GNU awk：

awk '{print $NF}' FPAT='[a-zA-Z0-9_-]{19,34}' file

$NF: contains last column

FPAT: A regular expression describing the contents of the fields in a record. When set, gawk parses the input into fields, where the fields match the regular expression, instead of using the value of FS as the field separator.

输出：

1mzr8lgf50p9z6p-7RyHn4XjnyKSvyyuE
