New line separator for each grep result (Even if grep outupt is null)

If file content is:

Quote:

echo -n "Host is:"; grep -h -E 'host_value' /file_path echo -n "IPAD is:"; grep -h -E 'Address_value' /file_path

How to force each grep output to be in a separate line even if the grep output is null? And how to replace null values with specific string such as 'No value for this parameter'.

For example, if the host_value is hostname but Address_value is null then output should be as below:

Host is:hostname
IPAD is:No value for this parameter
