Your description isn't at all clear. Why are you setting the input field separator to a comma if you aren't doing anything with any fields? If you're trying to print a line giving the name of the file followed by the contents of the file, try:

Code:

awk 'FNR==1{printf("From file %s:\n", FILENAME)}1' file1 file2

If you're trying to print files with the file's name at the start of each line from that file, try:

Code:

awk '{print FILENAME, $0}' file1 file2

If you're trying either of these on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk.

If neither of these are what you're trying to do, show us some sample contents for your two input files, give a full English description of the changes you want to make to the input, and show us the output you're trying to produce from those sample inputs.

The two code segments you have shown us do not even come close to doing what you described. And, the various versions of awk on most Solaris systems do not include a nextfile operator (and your description doesn't seem to need it even if your version of awk does include it).

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
