Anothere variation:
Code:
awk -F\| '{for(i=1; i<=NF; i++) if(i!~/[689]$/ && $i=="") {print; next}}' file

for fun, you could also do this, but it is less readable:
Code:
awk -F\| '{for(i=1; i<=NF; i=i==5?7:i==7?10:i+1) if ($i=="") {print; next}}' file

or this:

Code:
awk -F\| 'BEGIN{S[6]; S[8]; S[9]} {for(i=1; i<=NF; i++) if (!(i in S) && $i=="") {print; next}}' file

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
