Linux Adding filename and line number from multiple files to final file

Hi all,
I have 20 files (file001.txt upto file020.txt) and I want to read them from 3rd line upto end of file (line 1002). But in the final file they should appear to start from line 1.
I need following kind of output in a single file:
Filename Line number 2ndcolumn 4thcolumn
Quote:
1 1 23.01 119.00
1 2 56.00
.. ....
1 1000 -09.00 89.00
..
2 1
2 2
.. ....
2 1000
...
20 1
20 2
..
20 1000
I was able to remove first 2 lines from each file (starting with #) and getting only 2nd and 4th column. Here is the code:
Code:
cat *.txt | awk '{print $2, $4} | sed "/#\/d" > out.txt

Please guide me.
Thanks

NAME
x2sys_merge - Merge an updated COEs tables SYNOPSIS
x2sys_merge -Amain_COElist.d -Mnew_COElist.d DESCRIPTION
x2sys_merge will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second file should only contain updated COEs relatively to the first one. That is, it MUST NOT contain any new two tracks intersections (This point is NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had to recompute only the COEs between the edited files and the rest of the database. -A Specify the file main_COElist.d with the main crossover error data base. -M Specify the file new_COElist.d with the newly computed crossover error data base. OPTIONS
No space between the option flag and the associated arguments. EXAMPLES To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt SEE ALSO
x2sys_binlist(1), x2sys_cross(1), x2sys_datalist(1), x2sys_get(1), x2sys_init(1), x2sys_list(1), x2sys_put(1), x2sys_report(1) GMT 4.5.7 15 Jul 2011 X2SYS_MERGE(1gmt)
