awk within awk
Hi I am trying to execute below code

Code:
awk -F, 'BEGIN{print "STARTING"}$5 ~ /Match/ { if(NF==0) print "No Match"; else
{awk -F, 'BEGIN{
print "To: abc@123.com"
print "MIME-Version: 1.0"
print "Content-Type: text/html"
print "<html><table>"
print "<tr><td>Hi All,</td></tr>"
print "<tr><td>Below is the data</td></tr>"
print "<tr><td></td></tr>"
print "</table></html>"
print "<html><table border=1>"
print "<th>Data1</th><th>Data1</th><th>Data1</th><th>Data1</th><th>Data1e</th>"
}$5 ~ /Match/ {print "<tr>";for(i=1;i<=NF;i++){print "<td>" $i"</td>"};print "</tr>"}
END{
print "</table></html>"
print "<table><html>"
print "<tr><td>Thanks,</td></tr>"
print "<tr><td>All the best</td></tr>"
print "</table></html>"}' file1 | sendmail  -t}
}END{print "ENd of script"}' file1

But it gives error

Code:
awk: syntax error near line 2
awk: illegal statement near line 2
bash: print: command not found
bash: print: command not found
bash: print: command not found
bash: print: command not found
bash: print: command not found

bash: ./testing.sh: line 14: syntax error near unexpected token `('
bash: ./testing.sh: line 14: `}$5 ~ /Match/ {print "<tr>";for(i=1;i<=NF;i++){print "<td>" $i"</td>"};print "</tr>"} '

Please help

Yes you cannot do that. awk is not an awk command

That's not doing anything for you. That `if' will never evaluate to true. A record cannot have at least 5 fields to meet the $5 ~ /Match/ expression and have 0 fields to evaluate true in the if(NF==0)

You are right Aia, i needed NR==0.
I modified the code

Code:
awk -F, 'BEGIN{
print "To: abc@123.com"
print "MIME-Version: 1.0"
print "Content-Type: text/html"
print "<html><table>"
print "<tr><td>Hi All,</td></tr>"
print "<tr><td>below is the data</td></tr>"
print "<tr><td></td></tr>"
print "</table></html>"
print "<html><table border=1>"
print "<th>Data1</th><th>Data1</th><th>Data1</th><th>Data1</th><th>Data1</th>"
}$5 ~ /Match/ { if (NR==0) print "No data"; else print "<tr>";for(i=1;i<=NF;i++){print "<td>" $i"</td>"};print "</tr>"}
END{
print "</table></html>"
print "<table><html>"
print "<tr><td>Thanks,</td></tr>"
print "<tr><td>All the best</td></tr>"
print "</table></html>"}' file | sendmail  -t

Basically What I want to do is, only if data is there send the mail, else do not send the mail. How can I achieve this?

No. NR==0 will NEVER be true. Please show us a sample of your input file and tell us in English what you are trying to extract from that file into the mail message you're trying to send.

The condition will not be effective inside awk since data is piped to sendmail regardless.

Maybe

Code:
#!/bin/bash

content=$(awk -F, '$5 ~ /Match/' file.txt)

if [[ -n "$content" ]]; then
    echo "$content" | \
    awk -F, '
        BEGIN{
            print "To: abc@123.com"
            print "MIME-Version: 1.0"
            print "Content-Type: text/html"
            print "<html><table>"
            print "<tr><td>Hi All,</td></tr>"
            print "<tr><td>below is the data</td></tr>"
            print "<tr><td></td></tr>"
            print "</table></html>"
            print "<html><table border=1>"
            print "<th>Data1</th><th>Data1</th><th>Data1</th><th>Data1</th><th>Data1</th>"
        } 
        { print "<tr>";for(i=1;i<=NF;i++){print "<td>" $i"</td>"};print "</tr>"}
        END{
            print "</table></html>"
            print "<table><html>"
            print "<tr><td>Thanks,</td></tr>"
            print "<tr><td>All the best</td></tr>"
            print "</table></html>"
        }' | sendmail -t 
fi

Raw file
Code:
Rent,City,Car,Amount,Name
Pending,Chicago,BMW,4k,jack
Not pending,New York,Mercedes,Mary

So daily I would filter the file manually where the column rent would have records which are Pending so file I would have


Code:
Rent,City,Car,Amount,Name
Pending,Chicago,BMW,4K,Jack

Now I need to check Daily on this file with column Name and send mails to those guys whose name appears

So what is happening with above code is, even if the rent is not pendingn, but since email is mentioned in awk command it sends blank mails to Non pending Users

I am sure even the manual efforts can be done through awk, but am not too sure
