Thanks all. That helps a lot.

Can I use the above code like this:
Code:
count=`nawk '{n+=gsub("esprd","")}END{print n}' myFile`
if [ $count == 0 ] ; then
  echo success
else
 exit

I donno why I keep getting
Code:
pmugstart[8]: test: argument expected
for statement if [ $count == 0 ] ; then

Your shell might not have ==, try =.

Try echoing the value of $count to see what you actually get.

You can put that part inside awk too, actually, since you can return an exit status of 1 if n>0, which if reads directly, avoiding needing to use backticks:

Code:
if ! nawk '{n+=gsub("esprd","")}END{exit n>0}' myFile
then
        echo "failure"
        exit 1
fi

echo "success"

Help with grep & count
Thanks Corona688


Code:
if ! nawk '{n+=gsub("esprd","")}END{exit n>0}' myFile

Can gsub be used along with ignore case. Like how to make this work for esPRD/ESprd/ etc.I tried looking but didn't find one.

Thanks a lot in advance.

Code:
nawk '{n+=gsub("esprd","", tolower($0))}END{exit n>0}' myFile

This seems not to work as required.
My file is as follows:
Quote:
No.esPRD.Queue|No.Receive.Queue|||n|120|No_User||No_User|
No.Send.Queue|No.Receive.Queue|||n|120|No_User||No_User|
If I run this code
Code:
nawk '{n+=gsub("esprd","", tolower($0))}END{exit n>0}' myFile

The return value is 5. I thought the value would be 1.

Thank you.

Alternatively, perhaps try grep?
Code:
if grep -qi esprd infile
then 
  echo failure
  exit 1
else
  echo success
fi

I don't understand how you're getting any count from that code at all. It outputs no count! It just returns success if the count is zero, and error for anything else.
