It looks as if you want to concatenate the contents of the two files while skipping the first row of each file.
Getting everything but the first row of a file can be done in many ways, for example, since the question was tagged with awk,
awk 'FNR > 1' file
With awk, it's actually quite easy to do what you'd want to do with that exact awk program:
$ awk 'FNR > 1' file1 file2
4 5
5 6
7 6
1 4
FNR is a variable that awk maintains that holds the current record number (line number) in the current file. If FNR is strictly greater than 1, then the current line in the current file is not the first line of that file. A program with a condition like this in it will cause the lines for which the condition is true to be printed.
