I took it for a typo. Probably should be "change data content". If not, then I am at a loss as well.

one more question , if I have 10 files need to be update , would advise how can I bulk update these files and directly update it rather than output to screen ?

Check out sed -i

-i[SUFFIX], --in-place[=SUFFIX]
