Mine broke when I tried my suggestion of changing the {11} to {12}. Not sure why, but it did.

That’s because the class you used [\w+] had 2 issues. First you stated it should be a word character, thus one of the alphanumeric characters plus underscore, see boost documentation. So as it does not include a space, but the space and 11 characters were what you wanted to select (in your adjusted version with {12}), it wasn’t going to select any of the lines. You also could have replaced the + with a space character and you would have selected the lines.

Second issue was that the + you added did not mean as many of the \w as possible, but actually just a + character. So if you replaced one of those spaces before the 11 \w characters with a + character your regex would have worked on that 1 line with the quantifier of {12}.

Possibly, had you entered your regex into regex101.com the description may have alerted you to the mistake. So although it worked (on 11 characters) the premise behind it was unfortunately wrong.

But, and I fully intend to end on a positive note, it was a useful exercise for you. I too was once in your shoes. Sometimes you learn more by the mistakes you make. I often used regex101.com to find out the description, it really can be useful. Don’t forget though that as it uses a similar (but not the same) regex engine there can sometimes be differences.

You already asked that. Be patient, and keep the discussion there.

Your new question has nothing to do with “remove last word of each line”, and shouldn’t be asked in this discussion.

SEARCH (?-s).{12}$

While @guy038’s suggestion appears to remove 12 characters when only 11 characters were wanted for removal, he’s also eliminating the space character that comes before the final 11, which seems fine to me.

Why not this simple one :

SEARCH (?-s).{12}$

REPLACE Leave EMPTY

Regular expression checked

Possibly Wrap around checked

One click only on the Replace All button

On the off chance you actually did try, this is what I came up with while you were reading it. :)

Find what: (.*(?=(?<=)[\w+]{11}))(.*)
Replace with: $1
Search Mode: Regular Expression
Dot Matches Newline = NOT CHECKED

This will leave a space behind the last letter. If you want that gone too, I suspect you’ll have to up the {11} to {12}, but if there is no space there, you’ll chop off letters.
