Code:
set -x
sort file*
+ sort file file~ file1 file1~ file2 file2~ file3 file3~ file4

sort takes any number of files to work upon (up to certain system limits). So, if unquoted, /Users/unknown/files/* should work.

Code:
c=`head -n1 file | cut -d. -f3`
d=`head -n1 file | cut -d. -f4`
oct3max=4

while (( c <= oct3max )); do
	while (( ++d <= 254 )); do
		echo 134.123.$c.$d >> NewFile.txt
	done; d=-1; ((c++));
done

Note - the appending in this code will take increasing longer as NewFile.txt grows. Increasing oct3max too high will w/o optimizing appending will take a long time to run.
