How can I add a logic to awk to tell it to print 0 when encountering a division by zero attempted? Below is the code. Everything in the code works fine except the piece that I want to calculate read/write IO size. I take the kbr[j] / rs[j] and kbw[j] / ws[j]. There are times when the iostat data does not have any kbr or kbw.
I used this on an AIX machine and encountered the following error.

Hi,
The script below works okay and emails me the log in the end once the script completes but what I'm trying to do is to also notify me via an email as soon as the script encounters any error whatsoever.

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
