How to extract text with a certain condition with notepad?

[ani rodet]

Hello, I tried to extract and paste in another file a text that has the characters @ @ but I have not succeeded

tengo el texto

y@17text@mail.com:telephone1
y17text@mail.com :telephone12
y19@text@mail.com:telephone15
@y31text@mail.com:telephone1345
y1wtext@mail.com :telephone1789
@y15text@mail.com:telephone14567
y18text@mail.com :telephone12345

I need to extract those that have two or more @ paste them into another file

y@17text@mail.com:telephone1
y19@text@mail.com:telephone15
@y31text@mail.com:telephone1345
@y15text@mail.com:telephone14567

Try this:

Invoke Mark dialog (Search (menu) -> Mark…)
Find what zone: (?-s)^.*?@.*?@.+
Mark line checkbox: ticked
Wrap around checkbox: ticked
In selection checkbox: unticked
Search mode selection: Regular expression
Action: Press Find All button
Next action: Search (menu) -> Bookmark -> Copy Bookmarked Lines
Next action: Paste wherever suits you

Here’s how the regular expression part of it works:

(?-s)^.*?@.*?@.+

• [Assert position at the beginning of a line (at beginning of the string or after a line break character) (carriage return and line feed, form feed)][1 ] ^
• [Match any single character that is NOT a line break character (line feed, carriage return, form feed)][2 ] .*?
  • [Between zero and unlimited times, as few times as possible, expanding as needed (lazy)][3 ] *?
• [Match the character “@” literally][4 ] @
• [Match any single character that is NOT a line break character (line feed, carriage return, form feed)][2 ] .*?
  • [Between zero and unlimited times, as few times as possible, expanding as needed (lazy)][3 ] *?
• [Match the character “@” literally][4 ] @
• [Match any single character that is NOT a line break character (line feed, carriage return, form feed)][2 ] .+
  • [Between one and unlimited times, as many times as possible, giving back as needed (greedy)][5 ] +
