Try something like this

Code:
(
printf "To: hari1189@gmail.com\n"
printf "Subject:Disk Space Report\n"
printf "Content-Type: text/html\n"
printf "Content-Disposition: inline\n\n"
printf "<html>\n<body>\n"
df -g | awk 'NR>1&&($4+0)>70' | awk '
  BEGIN {print "<table border=\"1\" cellpadding=\"4\" style=\"border-collapse: collapse\">"}
  NR>1{
    print "<tr>"
    for( i = 1; i <= NF; i++ ) {
      printf "%s", "<td"
      if (i==4&&$i+0>80) printf " bgcolor=#FF3366"
      else if (i==4&&$i+0>70) printf " bgcolor=#FF6633"
      print ">" $i "</td>"
    }
    print "</tr>"
  }
  END { print "</table>" }'
printf "</body>\n</html>\n" ) | sendmail -t

Hi Chubler X:L,

This will work for one server , but am planning to redirect the result to a .HTML format for all 17 servers which am planning to collate in a single email body and bring it as a resulting output. your code works for single server were i got the email . Thanks for that Smilie

Could you please help me out to redirect the below code to a .HTML format were i can use the CAT command to open it up in a email body by giving the below command line.

Code:
cat <servername>.html |mailx -s " Disk space result" hari1189@gmail.com

So that i can collect all <servername.html> in a single email body and send it to the users.

The happy news is we have reached 80% of what we expected. Jus a small redirection of .HTML format will help us to finish this thread . Thanks all in advance.

Cheers
Hari
Code:
printf "<html>\n<body>\n" df -g | awk 'NR>1&&($4+0)>70' | awk '   BEGIN {print "<table border=\"1\" cellpadding=\"4\" style=\"border-collapse: collapse\">"}   NR>1{     print "<tr>"     for( i = 1; i <= NF; i++ ) {       printf "%s", "<td"       if (i==4&&$i+0>80) printf " bgcolor=#FF3366"       else if (i==4&&$i+0>70) printf " bgcolor=#FF6633"       print ">" $i "</td>"     }     print "</tr>"   }   END { print "</table>" }' printf "</body>\n</html>\n"

Firstly collect the required HTML for your tables on each server like this:

Code:
df -g | awk 'NR>1&&($4+0)>70' | awk '
  BEGIN {print "<table border=\"1\" cellpadding=\"4\" style=\"border-collapse: collapse\">"}
  NR>1{
    print "<tr>"
    for( i = 1; i <= NF; i++ ) {
      printf "%s", "<td"
      if (i==4&&$i+0>80) printf " bgcolor=#FF3366"
      else if (i==4&&$i+0>70) printf " bgcolor=#FF6633"
      print ">" $i "</td>"
    }
    print "</tr>"
  }
  END { print "</table>" }' > server1.html

The join them up for your email, with a empty paragraph between each like something like this:

Code:
(
printf "To: hari1189@gmail.com\n"
printf "Subject:Disk Space Report\n"
printf "Content-Type: text/html\n"
printf "Content-Disposition: inline\n\n"
printf "<html>\n<body>\n"
cat server1.html
printf "<p></p>\n"
cat server2.html
printf "<p></p>\n"
cat server3.html
...
cat serverN.html
printf "<p></p>\n"
printf "</body>\n</html>\n" ) | sendmail -t

Smilie THANKS A LOT !!! CHUBLER XL ..

YOUR CODE WORKED CHARMING !!

99% over now. I got the result but i jus want to add the server names in the table

Code:
df -g | awk 'NR>1&&($4+0)>70' | awk '   BEGIN {print "<table border=\"1\" cellpadding=\"4\" style=\"border-collapse: collapse\">"}   NR>1{
print "<tr>"
print "<td" printf "bgcolor=#gray" 
print ">" echo `hostname` "</td>"
print "</tr>"[/B]
 print "<tr>"     for( i = 1; i <= NF; i++ ) {       printf "%s", "<td"       if (i==4&&$i+0>80) printf " bgcolor=#FF3366"       else if (i==4&&$i+0>70) printf " bgcolor=#FF6633"       print ">" $i "</td>"     }     print "</tr>"   }   END { print "</table>" }' > server1.html

To bring the servername in the table , am i right with the RED colored area of the code. SO that i can split the tables with servernames and it will be easier.

Your help is highly commendable and thanks for the 99% completion . Thanks to all!!!

Cheers
Hari

Best bet is to pass hostname in as an awk variable and prepend it to the line.
Note that used% field is now #5, as hostname pushes all the fields over by 1:

Code:
df -g | awk -H=$(hostname) '
  BEGIN {print "<table border=\"1\" cellpadding=\"4\" style=\"border-collapse: collapse\">"}
  NR>1{
    $0= H " " $0
    print "<tr>"
    for( i = 1; i <= NF; i++ ) {
      printf "%s", "<td"
      if (i==5&&$i+0>80) printf " bgcolor=#FF3366"
      else if (i==5&&$i+0>70) printf " bgcolor=#FF6633"
      print ">" $i "</td>"
    }
    print "</tr>"
  }
  END { print "</table>" }' > server1.html
