he's got a >> there, not a >, so cp $i newfilename isn't the same :).
a better solution would probably be:
for i in *.TXT; do
cat $i >> newfilename && mv $i /tmp
done
(1) you can just do *.TXT; no need for `ls *.TXT`.
(2) the && checks the error code returned by cat, so that the mv is only
done if there was no errors.

ie
( for i in *.TXT; do cat $i >> newfile && mv $i /tmp; done ) 2> /dev/null
to make Jeff's last comment completely unambigious :)
(can you replace the () with {} for that loop? not sure if you can
redirect the entire loop to /dev/null if you don't run a subshell.)
