It finds lines ending with a space (/ \$/), and prints the number of spaces at the end of the line by subtracting the position of the first or all space at the end of the line (match(\$0, / +\$/) from the length of the line itself ( length).

The best place to start is the awk man page. (if I'd have done that(!) the solution might have been easier):

Quote:
match(s, r)
the position in s where the regular expression r occurs, or 0 if it does not. The variables RSTART and
RLENGTH are set to the position and length of the matched string.
