Shell Script to read hive table and send email

HI Team,
I am working on reading hive table and send email in email body using shell script, can you please help on fixing the errors: I have 6 columns in my hive table and trying to send the email in the mail body.
below script:

Code:
#!/bin/bash
hive -e 'SELECT count(*) from db.table' > output.txt
sed -i 's/\t/,/g' $tmp/output.txt

nawk BEGIN{
FS=","
print  "MIME-Version: 1.0"
print  "Content-Type: text/html"
print  "Content-Disposition: inline"
print  "<HTML>""<TABLE border="1"><TH>TB1</TH><TH>TB2</TH><TH>TB3</TH><TH>TB4</TH><TH>TB5</TH><TH>TB6</TH>" }
 {
printf "<TR>"
for(i=1;i<=NF;i++)
printf "<TD>%s</TD>", $i
print "</TR>"
 }
END{
print "</TABLE></BODY></HTML>"
 }
file-to-convert.csv > file.html
echo "output.txt" | mailx -s "output" -a output.txt email.com

I am missing something here...
./countemail.sh: : Is that the script you gave us ?
Since when a csv file is a script?
Code:
 file-to-convert.csv > file.html

# 3  
yes countemail.sh is the script and below is the code:

Firstly the posted script seems to be missing single quote at the start of the awk code, and two single quotes at the end.

Also your system is reporting that nawk is not installed nawk is usually required on Solaris systems, you don't report your OS but my guess is a non-Solaris system. Try using awk or gawk instead.

Try:
Code:
#!/bin/bash
hive -e 'select * FROM db.table' > output1.csv
sed -i 's/\t/,/g' output1.csv
awk 'BEGIN{
FS=","
print  "MIME-Version: 1.0"
print  "Content-Type: text/html"
print  "Content-Disposition: inline"
print  "<HTML>""<TABLE border="1"><TH>project_name</TH><TH>schema_name</TH><TH>table_name</TH><TH>partition_col_name</TH>"}
 {
printf "<TR>"
for(i=1;i<=NF;i++)
printf "<TD>%s</TD>", $i
print "</TR>"
 }
END{
print "</TABLE></BODY></HTML>"
 }' output1.csv > file.html
echo "file.html" | mailx -s "output" -a file.html email
