Wildcard comparrison question

| Hi
I have a quick question that has stumped me. I want to report on files
that I have on the system. When it finds files with the name
containing SNL I want to perform report the information invalid and
stop processing that file, for all other files I want to run a awk
command that will extract certain information and report the outcome.
Now I am able to perform these commands separtly but I am unable to
get them to work together sucessfully.
An example of my code is as follows
ls -rt /*.ok /*.err|while read fname
do
# Output the file contents and look for the XML tag to identify the
start positi
on (Stored in RSTART)
# Next we look for the end tag and calculate the total length of our
contents an
d print the result
# if we find anything. If we don't then that search line will not get
printed.
echo $fname | awk '!/\.SNL/ { notsent = "|||||||"$1"||not sent|";
print notsent
}'
# The following doesn't work hence the question
<<<<<<<<<<<<<<<<<<<<<<<<
if [ "$notsent" = "true" ]
then
echo "|||||||$fname||not sent|"
else
cat $fname|awk ' function extract(extractSrc,extractPattern) {
if (match(extractSrc, "<"extractPattern">"))
.......
As you can see the first awk statement uses output from echo file the
second uses output from cat.
Many thanks in advance

You never set the shell variable $notsent. You assigned to an awk
variable, not a shell variable. If you want to capture that in the
shell, you need to do something like:
notsent=`echo $FNAME | awk ...`
Although awk seems like way overkill for this, why not:
case "$fname" in
*.SNL*) notsent=true ;;
*) notsent=false ;;

The problem is that $fname just contains the file name, not the complete
pathname. E.g. if the file is /foo.ok/file.SNL, you'll do "cat
file.SNL" instead of "cat /foo.ok/file.SNL". Run "ls -rt /*.ok" and
look at the output to see why.
Try changing your ls command to:
ls -rt /*.ok/* /*.err/* | while read fname
And if you do this you
