Better solution with regex replace:

(?!^.SOMETEXT.$)^.+\r?\n
And replace with nothing

Hello, @hamada-re3oo and All,

I suppose that, due to the Markdown syntax, in our forum, some star symbols ( * ) miss in your regex ;-))

So, in order to delete any line, even empty, of a file, which does NOT contain a specific text, a correct and simplified version could be :

SEARCH (?-is)^(?!.*Some text).*\R , for a sensitive to case search

OR

SEARCH (?i-s)^(?!.*Some text).*\R , for an insensitive to case search

REPLACE Leave Empty

For instance, the regex (?-is)^(?!.*Fix).*\R would delete any line, even empty, of the change.log file, which does not contain the word Fix, with that exact case

Best regards,

side note on posting:

if you want to post text with special characters,
you can type it it in between `` back ticks (accent grave)

example:

`my text with special *characters* **&%$&**`

will be displayed correctly as
my text with special *characters* **&%$&**
instead of
my text with special characters &%$&
