regexp to get first line of string

Hi everybody

Code:

for file in *
#Bash performs filename expansion
#+ on expressions that globbing recognizes.
do
	
	output="`grep -n "$1" "$file"`"
	echo "$file: `expr "$output" : '\(^.*$\)'`"

done

In the above bash script segment, I try to print just the first line of string named output.

I've got a problem with the regexp. It returns the full string which is multilined.

Thank you in advance for any help
