Linux sed can't read the file that's right there

Question

grep -r -l --include=*.{html,js,css} "\bAA\b" . | xargs -0 -n 1 sed -i -e "s/\bAA\b/BB/g"

When I ran the above command, I got the following error:

sed: can't read ./login.html : No such file or directory

This is rather odd as I am able to vi ./login.html

I don't understand why am I getting this error. Please help. Thanks.

Answer 1

You shouldn't be using -0 with xargs unless the previous command actually uses NUL to delimit its output, which grep does not unless you use -Z. Therefore it's looking for "./login.html " and not "./login.html" (note the space).
