Regex: Select only the line 27 (mark a particular line)

Vasile Caraus

hi, how can I select a particular line with regex, for ex. line 27 on text document?

Scott Sumner

You could use the technique presented here:

The formula below works in sublime text editor. But I don’t know why is not working in notepad++. Maybe guy038 will find the solution for notepad++.

\A(?:^.*$\n){3}\K^.*$ This regex will select line 4 from text.

So If I want to select line 6, I will put {5}

Anyway, can anyone make this regex formula to work also in notepad++ ?

Using @guy038’s technique presented in the link pointed to by @scott-sumner e.g. select line 27 in text document: (?-s)(.*\R){26}\K.*\R

SUPER ! Thanks.

\R cause some problem at replace, so is much better \r at final

(?-s)(.*\R){2}\K.*\r

MAPJe71

some problem

What exactly?

Vasile Caraus

there is one bug in this formula (?-s)(.*\R){26}\K.*\R or (?ms)(.*\R){26}\K.*\R

It is not unique. It will selects all the multiple of line I choose. (If I press “Replace All” with something)

in this case, it selects the 27 row, but also selects 54, 81, 108…etc

The answer is in @guy038 post here.

Hint: 2 x 27 = 54, 3 x 27 = 81.

Vasile Caraus

hello MapJe27. I am sorry, I cannot find an answer in that post. There, I see a regex that find a line between columns. But not an unique line, that can be use for Replace All in many documents.

maybe you can help me a little bit.

Notes :
Always locate your cursor at the beginning of your file, first

@Vasile-Caraus said in Regex: Double your words:

If I want to replace one single line in many files

It would been a lot easier/faster if you had shared this information from the start in this topic!

I can’t say it’s not possible with regular expressions, I just don’t know how. I’d use a script with one of the script plugins (PythonScript, LuaScript).

Hi Vasile Caraus,

Just see my solution, below, in topic about replacing by multiple values of a same line :
