      I need to grab raw value of Reallocated sectors count:

      5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0

      In dependent item I tried to use the following regex:

      5 Reallocated.+\s([0-9]+), \1
      

      But that returned the following string(the first value on the NEXT line actually):

      9
      

      I then switched to

      5 Reallocated.+ ([0-9]+), \1
      

      And that worked and returned me '0'

      Could it be that it is because \s doesn't match space and only newline chars?
      and according to http://www.pcre.org/original/doc/html/pcrepattern.html
      it should match space as well.

      For example, online tool https://regex101.com/ returns 0 for both regexes.

      Correct if I'm wrong
