Question

I have a for loop in bash that is;

for Names in `grep "name" $people`
do
    echo "name is $name"
done

How can I have an if statement that says something like;

for Name in `grep "name" $people`
# Make sure we found some names
if [ "count of $Name=0" ]
then
    echo "no names found"
fi

# Else, if we did grep out a list of names, print them
do
    echo "name is $Name"
done

Perform the grep first and store its result in a variable. Then check whether something is returned, e.g., with wc. If so, run the loop with the result of grep.
