Adding a varying number of fields to an incomplete line might be achieved like

Code:

awk '
NR == FNR       {A[$2] = $0
                  next
                }
!A[$1]          {A[$1] = sprintf ("%*s", 14-NF, "-")
                 gsub (/ /, "-\t", A[$1])
                }
                {print $0, A[$1]
                }
' file2 file1
