awk version:
Code:
awk 'NR==FNR{A[$1]; next} FILENAME!=ARGV[1] && $1 in A{print $0,FILENAME}' file * | sort -k1,1 -k4,4

@pamu: probably need to fix $x to avoid incomplete matches, for example:
Code:
grep "^[[:space:]]*$x[[:space:]]"

and
Code:
grep -v "^file:"

also, the awk and the second grep could be placed outside the loop for efficiency...:
Code:
done < file | grep -v "^file:" | awk -F: '{print $2,$1}' > output_file

or
Code:
done < file | awk -F: '$1!="file"{print $2,$1}' > output_file

--
Neither of our solutions will work if there are too many files in the directory...

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
