OT: merge two files

[Kent West <westk@acu.edu>]

I want to merge the contents of one file with the bottom X lines of 
another. This works:

cat file1 > EndResultFile && tail +20 file2 >> EndResultFile

Is this adequate, or is there a better way to do it?

(Sorry I'm asking a programming question on Debian-User, but you folks 
are sharp, and I get confused with such things as piping and 
redirection, etc.)

Thanks!
