Hi Group, The following is a very simple program but I'm not able to get the output. $ awk -f summary.awk input.txt where input.txt contains a single line John Mary Anthony Suresh Sam summary.awk contains: END { print NR print FILENAME print $0 } The output gives NR as 1, FILENAME as input.txt, BUT it is NOT printing anything for $0. I'm working on SUN solaris machine. -SP

$0 is only set within the line-oriented execution; It may be non-portable to assume that NR and FILENAME are. Assuming what you want is the last line, try: { z=$0 n=NR f=FILENAME } END { print n print f print z }
