Get 10 lines before specific word with regular Expression

Mohammed Osama

I used this regx (.*\R){10}^.*succeeded.*\R
to get the previous 10 lins before Succeeded word but the output not correct it retrieve only 4 cases even i have 7 cases matching,
but its working as excepcted if i change 10 lines to 6 lines
(.*\R){6}^.*succeeded.*\R
so is there any restriction for this.

@mohammed-osama ,

Depending on your setting of .-matches-newline, your multiple .* will match more text than you think. Turn off the checkbox, or prefix your regex with (?-s) , and my guess is that it will work as you expect.

Oh, also, you can make the one .* before succeeded non-greedy with by using .*? instead

I turned of the checkbox and used this
(.*\R){10}^.*?succeeded.*\R

That’s not sufficient for us to be able to help you.

Ok Thank you

So you just give up?
Peter was hinting you need to supply more information…to get more help, which people do want to provide (but can’t because “doesn’t work” on its own isn’t really solvable).

@mohammed-osama ,

After you gave up, I made a file containing sixteen copies of:

twelve
eleven
ten
nine
eight
seven
six
five
four
three
two
one
this line succeeded in being matched

When I used the regex you quoted, it showed 16 matches, and each match was the line with “succeeded” plus the 10 lines before it:

As far as I can tell, that “worked”, based on the problem statement you made in your posts.

When you say “but not working”, when it works for us, you have to provide more than “not working” in order for us to understand how your requirements differ from those that you’ve stated.

The “Useful References” I linked were to help you ask your question better. and would be useful to help you ask in a way that we can better understand what you want. The “Please Read Before Posting” gives important information about how to format a post, and links to how to format your text in such a way that we can read it (rather than requiring a moderator go in and fix your posts so that the regex are readable; as a moderator, I was willing to do that twice, because I thought it made your questions more accessible, which would make it more likely that you would get your help). The “Template…” is just that, a template that you can use to easily format your search/replace questions so that you give us both example data and what you have already tried. The last two were additional reading that will help you in the future.

I went to a lot of effort to make sure you got good help, and yet the extent of your reply was “but not working”. If you try harder, we can continue to try helping. If you give up, then you will never learn how to do what you want. It’s really up to you.
