You didn't tell us if there is any naming convention on the file names, so it is difficult to suggest a loop where you don't have to name the possible file names but instead generate them. In any case the loop you use should NOT be a for-loop, because it can break if a file glob expands to something you didn't foresee.
Instead, use a while-loop, like this:
To add a file to another without the first two lines you can use "sed":
So, putting it together, your script could look like this - you will have to supply the correct file glob instead of "*input", which i used for demonstration purposes:
This will copy the first input-file (preserving the 2-line header) and cut off the header of any following file. "if [ -e <filename> ]" means: if "<filename>" exists and is a regular file. Because any eventually existing output file is deleted prior to the loop this is not the case with the first file.

make_sockdfr
MAKE_SOCKDFR(8) System Manager's Manual MAKE_SOCKDFR(8)NAME
make_sockdfr - Generates frozen route file for SOCKS server
SYNOPSIS
make_sockdfr [infile [outfile] ]
DESCRIPTION
make_sockdfr reads in a plain-text route file for the SOCKS server and produces a frozen route file as the output.
Both arguments are optional. The default for infile is /etc/sockd.route; the default for outfile is /etc/sockd.fr. You may specify infile
while omitting outfile, but you cannot specify outfile without also speficying infile.
The contents of the frozen route file is essentially the memory image of the parsed input file. Using the frozen route file can reduce the
start-up delay of the SOCKS server program since it no longer has to parse the file contents.
When the SOCKS server starts, it always looks for the frozen route file /etc/sockd.fr first. If that file is not found, it then tries to
use the plain-text route file /etc/sockd.route. If you use frozen route file, you must remember to run make_sockdfr every time after you
modify the plain-text file or the SOCKS server will continue to use the frozen version of a previous route file.
To find out the contents of a frozen route file, use dump_sockdfr.
FILES
/etc/sockd.fr, /etc/sockd.route
