删除 vCard 文件中的重复记录

Question

我有一个包含数千个联系人记录的 vCard 文件。此文件已损坏，已为每个用户添加个人 phone、工作和额外记录的副本。

如何清除重复项？

我使用了在Whosebug中看到的以下解决方案，但并没有解决问题，因为并非所有重复项都连续出现。

perl -ne 'print unless (defined($prev) && ($_ eq $prev)); $prev=$_'

导致：

...
TEL;TYPE=WORK,VOICE:(111) 555-1212
TEL;TYPE=HOME,TYPE=VOICE:(404) 555-1213
TEL;TYPE=WORK,VOICE:(111) 555-1212

删除所有重复行的最简单方法是

perl -ne 'print if !$seen{$_}++'

如果您想单独处理每个 BEGIN:VCARD 部分，

perl -ne '%seen = () if /\bBEGIN:VCARD\b/; print if !$seen{$_}++'
