bash script to append string to multiple files in same directory

Question

Is there a way to write a BASH script that will append a string to every file in a directory?

e.g., I want to append the string "test" to every .html file in the current working directory I'm in; something like:

echo "test" >> *.html

But of course this doesn't work.

Answer 1

Nevermind, I figured it out.

#!/bin/sh

for f in *.html ; do
    echo "test" >> $f
done

Answer 2

sed -i.bak '$a append' *.html
