Count Number Of lines in text files and append values to beginning of file

Hello,

I have 50 text files in a directory called "AllFiles"

I want to make a program that will go inside of the "AllFiles" Directory and count the number of lines in each individual text file. Then, the program will calculate how many more lines there are over 400 in each text file and append this information to the beginning of each text file.

For example, lets say i have 5 files in a directory in the "AllFiles" directory:

file1.txt ---has 500 lines
file2.txt ---has 600 lines
file3.txt ---has 550 lines
file4.txt ---has 700 lines
file5.txt ---has 480 lines

The result of the program should be this:

The first line of file1.txt should read: "there are 400 lines in this file and 100 bonus lines"
The first line of file2.txt should read: "there are 400 lines in this file and 200 bonus lines"
The first line of file3.txt should read: "there are 400 lines in this file and 150 bonus lines"
The first line of file4.txt should read: "there are 400 lines in this file and 300 bonus lines"
The first line of file5.txt should read: "there are 400 lines in this file and 80 bonus lines"

Is there any way that i can do this using the command prompt?

I have tried using 'sed' to do this, but i guess i am missing several necessary libraries. I have GNUwin32. I downloaded the program from gnuwin32DOTsourceforgeDOTnet/packages/sedDOThtm. I downloaded and installed the "completed package, except resources" file and "resources" file.

But, i really have no idea how to use sed. I have tried a couple command prompt line items, but most of them end up in errors.

I don't have visual studio, but i do have the Microsoft office Visual Basic editor, and i have tried a few basic things to do this with no success.

Any ideas would be greatly appreciated.

If it matters, my computers operating system is Windows 7.

LEARN ABOUT FREEBSD

comm

COMM(1) 						    BSD General Commands Manual 						   COMM(1)

NAME

     comm -- select or reject lines common to two files

SYNOPSIS

     comm [-123i] file1 file2

DESCRIPTION

     The comm utility reads file1 and file2, which should be sorted lexically, and produces three text columns as output: lines only in file1;
     lines only in file2; and lines in both files.

     The filename ``-'' means the standard input.

     The following options are available:

     -1      Suppress printing of column 1, lines only in file1.

     -2      Suppress printing of column 2, lines only in file2.

     -3      Suppress printing of column 3, lines common to both.

     -i      Case insensitive comparison of lines.

     Each column will have a number of tab characters prepended to it equal to the number of lower numbered columns that are being printed.  For
     example, if column number two is being suppressed, lines printed in column number one will not have any tabs preceding them, and lines
     printed in column number three will have one.

     The comm utility assumes that the files are lexically sorted; all characters participate in line comparisons.

ENVIRONMENT

     The LANG, LC_ALL, LC_COLLATE, and LC_CTYPE environment variables affect the execution of comm as described in environ(7).

EXIT STATUS

     The comm utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     cmp(1), diff(1), sort(1), uniq(1)

STANDARDS

     The comm utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

     The -i option is an extension to the POSIX standard.

HISTORY

     A comm command appeared in Version 4 AT&T UNIX.
