Alternatively, you could use a for loop and ed, instead of resorting to temp files or gnu extensions:

for f in Export???.dat; do
printf %s\\n '1,$s/Absolute velocity/Pixel shift/g' w q | ed...

If yours is a GNU SED then
sed -i 's/Absolute velocity/Pixel shift/g' Export000.dat
else you could send the output to a temp file and move the temp file to original file name.
