You said that you want the same header and trailer as the original file!

By the way I missed skipping header & trailer, which you can do using awk:
Code:
lines=$( wc -l < filename )
awk -v L=$lines 'NR>1&&NR<L' filename > filename_data
split -d -l 1000 filename_data filename_out

Use wc to calculate line count and append it as trailer to each file:
Code:
head -1 filename > header

for file in filename_out*
do
   cat header ${file} > tmp
   wc -l < ${file} >> tmp
   mv tmp ${file}
done

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
