ummm, try something like
(cat B; tail -`wc -l fileB | awk '{print $1 + 1 }'` fileA) >> newA

Experiment before you overwrite !!! This will append the entire file A to file 
B if file B is bigger than A.

it depends on exactly what you need to do.  if you can literally append to
a file...

    bourne shells (sh, ksh, bash)

	for file in *.html; do
	    cat disclaimer.txt >> $file
	done

    c shells (csh, tcsh)

	foreach file (*.html)
	    cat disclaimer.txt >> $file
	end

most html files have a </body> and </html> at the end though, right?  :)
i usually use sh, sed, or awk scripts to search for the end tags and insert
a block of text.  it helps a lot if all your html files are laid out
consistently.  

	#!/bin/sh
	#  written off the top of my head, usual disclaimers apply.

	for file in *.html; do
	    ( while read line; do
		if [ "$line" = "</body>" ]; then
		    cat disclaimer.txt >> $file.new
		fi
		echo "$line" >> $file.new
	    done ) < $file
	    mv $file.new $file
	done

bonus clue:  make a backup tar of everything before making scripted
changes.  not much sucks worse than trashing all your files by mistake.  :)

It can suck even less: whenever I change files that I rely on, I use
sort of version control to let me incrementally back out any changes
I've made.  I'd stick in some RCS CheckOut and CheckIn commands before
and after the editting:

#!/bin/sh
#  written off the top of my head, usual disclaimers apply.

for file in file? ; do
    co -l $file
    ( while read line; do
	if [ "$line" = "</body>" ]; then
	    cat disclaimer.txt >> $file.new
	fi
	echo "$line" >> $file.new
    done ) < $file
    mv $file.new $file
    ci $file <<EEOOFF
