grep and awk showing filename in loop
I am attempting to grep a list of files for a string an and then only extract the 3rd and 4th field of from the line. That's easy. But I want to prefix the line with the filename that the information came from.

for filename in `ls -1 *.txt'
do
grep search_text $filename | awk '{print $3" "$4}'
done

This displays the 3rd and 4th field of all lines in the list of files as in:
Field3 Field4
Field3 Field4

but I would like to see
a.txt Field3 Field4
b.txt Field3 Field4

Can somone give me a clue on how to do this.

Thanks,
Scott

bzfgrep

BZGREP(1)						      General Commands Manual							 BZGREP(1)

NAME

       bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression

SYNOPSIS

       bzgrep [ grep_options ] [ -e ] pattern filename...
       bzegrep [ egrep_options ] [ -e ] pattern filename...
       bzfgrep [ fgrep_options ] [ -e ] pattern filename...

DESCRIPTION

       Bzgrep  is  used to invoke the grep on bzip2-compressed files. All options specified are passed directly to grep.  If no file is specified,
       then the standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and  fed	to
       grep.

       If  bzgrep  is  invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, bzgrep
       uses it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	bzgrep string files
	   for csh: (setenv GREP fgrep; bzgrep string files)
