Also if possible want to delete lines containing . like

@Sameh-El-Desoki ,

Welcome to the Notepad++ Community Forum. I will append some useful generic information at the end of this post for how to ask your question in a way that will improve the quality of answers that you get, and provides links for how to learn how to do the fancy search/replace on your own rather than relying on us. Avail yourself of that advice.

I will do my best to answer based on the information you have given.

You will want to use the “regular expression” search mode.

Your first request said,

I want to delete lines containing https://***:2083

The notation you gave was very nearly the regex expression needed for mathcing that portion. .+ will match 1 or more of any character. If you restrict it to “as few as possible”, .+?, then it will go from the https:// to the first :2083 in the match.

Then, all you have to do is add the regex syntax for grabbing the first part of the line and last part of the line (including newline or end of file), and bring it all together

FIND = ^.*?https://.+?:2083.*?(\R|\Z)
REPLACE = empty
Search Mode = regular expression
Uncheck . matches newline
REPLACE ALL

Translates:

keep
https://bnasicoasdasasdasfo.biz:2083|cthakzzq|Ch3
keep
https://bnasfasfasdaso.com:2083|vichlvcl|Ch
keep
https://bodasdasdasdlutions.com:2083|hd
keep

into

keep
keep
keep
keep

if possible want to delete lines containing . like domain.com or domain.net

To match a literal . character in a regex, escape it like \.

So the pattern will be start-of-line, 0 or more chars, literal ., 0 or more chars, end-of-line/end-of-file

FIND = ^.*?\..*?(\R|\Z)
REPLACE = empty
Search Mode = regular expression
Uncheck . matches newline
REPLACE ALL

translates

This line has no dot
This ends in dot.
.This started in dot
domain.com
domain.net
no dot

to

This line has no dot
no dot

Please note that better examples, with lines to delete and lines to keep, would help us confirm the regex works before we post our answer, rather than you having to tell us, “no, I really meant xxx”.

Please note that this forum is not a “do my data transformation for me”, or even a “generic regex help forum”. We will give new users a couple of rounds of regex help, but really, this forum is about so much more than just “make my data change from X to Y”. You will get better help if you show an effort and willingness to learn.

Do you want regex search/replace help? Then please be patient and polite, show some effort, and be willing to learn; answer questions and requests for clarification that are made of you. All example text should be marked as literal text using the </> toolbar button or manual Markdown syntax. To make regex in red (and so they keep their special characters like *), use backticks, like `^.*?blah.*?\z`. Screenshots can be pasted from the clipboard to your post using Ctrl+V to show graphical items, but any text should be included as literal text in your post so we can easily copy/paste your data. Show the data you have and the text you want to get from that data; include examples of things that should match and be transformed, and things that don’t match and should be left alone; show edge cases and make sure you examples are as varied as your real data. Show the regex you already tried, and why you thought it should work; tell us what’s wrong with what you do get. Read the official NPP Searching / Regex docs and the forum’s Regular Expression FAQ. If you follow these guidelines, you’re much more likely to get helpful replies that solve your problem in the shortest number of tries.
