Of course you can say that, some people would bow to your attention to
detail, I tend to be moody and would think, most likely unfairly, that
you are being pedantic for the fun of it.

You can use common sense interpreting the one liner requirement (which
I think most people with some basic understanding of scripting would
interpret in a reasonable manner) and that way live happily with the
rest of humanity.

It would have been even more interesting to mention a possible
solution taking care of the problem you correctly highlight:

In bash:

for i in "*.html" ; do sed -i -e 's/fish/chips/g' $i ; done
