Using awk to determine if field value is valid
Hi Forum.

I tried to search the forum posts for an answer but I haven't been able to do so for what I'm trying to accomplish.

I have the following source file:
Code:
11936385~TFSA|11936385|4431|3401458067|10/09/1982|25.00|IBSBONUS|3200|||||CASH|
3401458067|1005|
21936385~TFSA|11936385|4431|3401458067|10/09/1982|0|IBSBONUS|3200|||||CASH|3401
458067|1005|
31936385~TFSA|11936385|4431|3401458067|10/09/1982|A|IBSBONUS|3200|||||CASH|3401
458067|1005|
41936385~TFSA|11936385|4431|3401458067|10/09/1982||IBSBONUS|3200|||||CASH|34014
58067|1005|

Field#6 has to be a dollar amount or count value greater than zero. So for this example, first record is valid while the last 3 records are not valid.

This is the code that I have so far but it's not returning the correct expected results:
Code:
awk -F"|" '$6=="" || $6=="0" || $6 !~ /^[0-9]*.[0-9]*$/ {print $0}' filename

Thanks for your help.

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
