    sed -ne 's/^.*\(word_here\).*$/\1/p' < file

    BTW, why not simply

            if grep -q word file
            then
                    # word was present in file
                    bla
                    bla
            fi

    Or "if ! grep -q word file" if you want to do something if word
    wasn't present in file.
