Hi Summer,
Your code is able to work but some how the sequence of display seems to be jumbled up. " 0004 " should be at the last line but it came to the 1st line.

Below is my output using your code:

$ awk -f myawk data

0004 k= 6
0001 k= 27
0002 k= 1
0003 k= 1

GIT-MAILSPLIT(1)						    Git Manual							  GIT-MAILSPLIT(1)

NAME

       git-mailsplit - Simple UNIX mbox splitter program

SYNOPSIS

       git mailsplit [-b] [-f<nn>] [-d<prec>] [--keep-cr] -o<directory> [--] [(<mbox>|<Maildir>)...]

DESCRIPTION

       Splits a mbox file or a Maildir into a list of files: "0001" "0002" .. in the specified directory so you can process them further from
       there.

	   Important
	   Maildir splitting relies upon filenames being sorted to output patches in the correct order.

OPTIONS

       <mbox>
	   Mbox file to split. If not given, the mbox is read from the standard input.

       <Maildir>
	   Root of the Maildir to split. This directory should contain the cur, tmp and new subdirectories.

       -o<directory>
	   Directory in which to place the individual messages.

       -b
	   If any file doesn't begin with a From line, assume it is a single mail message instead of signaling error.

       -d<prec>
	   Instead of the default 4 digits with leading zeros, different precision can be specified for the generated filenames.

       -f<nn>
	   Skip the first <nn> numbers, for example if -f3 is specified, start the numbering with 0004.

       --keep-cr
	   Do not remove 
 from lines ending with 
.
