The NR%10 will distribute the lines as evenly as possible between 10 files, writing every single line to the next (rotating) file, independent of the total number of lines.

If the open file count is less then the max. allowed open files, close(f) is not indispensable, although it were good style - normally. In your case of 1E7 lines, it would mean 1E7 open and 1E7 close operations, slowing down processing considerably. Me, I'd forgo it.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
