In this simple tutorial you will learn how to delete or remove duplicate lines from a text file when you have a list of something (products, names, domains, e-mails etc) using Sublime Text.
To make a fast analysis of your duplicated lines, you should first order your list alphabetically. For example if you have a list of names, when you sort them, duplicates will appear right under the original name and in this case you can remove duplicate lines.
This method is great and fast when you have a short list of things and you want to remove duplicate lines manually. Below I will give you an example.
If you have a very long list and you don't have time to check every row manually, you can also remove duplicate lines by using Permute Unique Lines.
For long lists with duplicates, you can automatically delete them by using Permute Unique Lines from Sublime. To do that, go to "Edit - Permute Lines - Unique".
The results will obviously be without duplicates and Sublime did all the work in one easy step. Check the image below.
This method is also great and useful to delete or remove duplicate lines of a list with domains, products and many others things. You can download Sublime Text from here.
