"for i in *" can be used to loop over all file names in the current directory.

Use this to write shell commands which check whether each file in the current directory contains the string 'good' in the opinion of grep.

For each file containing 'good', output a line of the form

        file is good... file is *very* good.

Solution:

for i in *
do
    if grep good "$i" >/dev/null
    then
        echo "$i" is good... "$i" is \*very\* good.
    fi
done
