Needing direction using REGEX in Notepad++ to find length of characters in line that also contains spaces

I have a TEXT file where I have 4700 lines of a 30 character value. The numerical characters are in position 1 through 8 and then there are only spaces supposedly after. I am using REGEX in NOTEPAD++ to find 2 separate scenarios:

  1. I would like to find if there exists on any line of my text file the length of characters in position 1-8 that are less than 6.
  2. Are there any lines in my text file that have a length > 30. I think I found the answer to this but would like some confirmation as I am not picking up anything in my results. Here is my what I'm using in NOTEPAD++ find these values: .{30, }

Any help/direction would be appreciated. Thanks.

Here is a sample of what my file looks like:

Solution

  • Number 1 would be ^\d{0,5}\s+\n

     ^ matches the beginning of the string or line
 \d digit
 {0,5} matches quantify or proceeding token
 \s whitespace
 + quantifier matches 1 or more
 \n is a new line

    Number 2 would be ^.{31,}

     ^ matches the beginning of the string or line
 . matches any character but line breaks
 {31,} matches any line that is 31 characters or greater.
