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

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

Or, using a here document:
Code:
for f in Export???.dat; do
    ed -s "$f" <<'EOED'
        1,$s/Absolute velocity/Pixel shift/g
        w
        q
EOED
done
