@Raoul-Emil
Find/replace form, go to the Mark tab (Ctrl+M using default keyboard shortcuts)

Settings:
Bookmark line: ON
Purge for each search: doesn’t matter (I recommend on; it’s a useful default)
Backward direction and Match whole word only: disabled b/c using regular expressions
Match case: doesn’t matter
Wrap around: on
Search mode: Regular expression

FIND: \[[012]\]:
This will match an open squarebrace, the digit 0, 1, or 2, a close squarebrace, and a colon
Click the Mark All button. This will bookmark the lines that you want to keep.
From the main menu: Search->Bookmark->Remove Non-Bookmarked lines

This will remove all the lines you don’t want.

Hello, @mark-olson, @raoul-emil and All,

Mark, in your reply to @raoul-emil, I suppose that the string to find and mark is :

[\\[012\\]]:    ( and not [[012]]: )

Best Regards,

guy038

P.S. :

To understand your error, refer to :

My columns are from [0] to [30]. If i want to find by using [[012]]: expression, there will be also marked the numbers [10],[11] and [12] , but i want them deleted.
I want to mark only the rows with [0], [1] and [2].
Anyway,i can mark with normal text,no need for regular expression. But i didn’t know about the mark feature.

Hello, @raoul-emil, @mark-olson and All,

Ah…, OK. In that case, search and mark, using this regex syntax :

\\[0\\]|\\[1\\]|\\[2\\]

Best Regards,

@Mark-Olson said in Delete specific lines in file:

FIND: [[012]]:

Yeah, I’m aware that my regex was wrong.

I intended to enter \\[[012]\\], but apparently even after the recent upgrades to the forum it still has the issues with escaped squarebraces.

I had to test to see if the issue was still there, but didn’t have time to fix my post after it came out wrong.
