If duplicate within brackets, delete one of the lines

Hi i have a long list of items (~6k), that comes in this format:

'Entry': ['Entry'],

What i want to do, is if within the first bracket, the words match, i.e.:

'ACT': ['KOSOV'],

'ACT': ['STIG'],

I want it to leave only one of the entries, it doesn't matter which entry the first the second or whatever, i just need it to leave one of them.

If possible I would like to accomplish that by sublime, or notepad++ using regexp and if there is no way then do whatever you think is best to solve this.

UPD: The AWK command did the job indeed, thank you

You can't solve this using just regular expressions. You either need to remember all entries you've seen so far while scanning the text (would require writing a small utility program, probably), or you could sort the entries and then remove any repeated entries.

If you have a sorted file, then you can solve it using a regular expression, such as this one:

^(([^:]+):.+\n)(?:\2.+\n)+

Replace with \1. See it in action here
