While Loop with if else condition
Hi,
I was trying to write a shell script which reads csv file and sends mail in html format along with tables. Hope i have completed 1st part , but while sending mail i was trying to highlight some rows in the table based on the egrep outcome. If the string exists in line/INPUT, i am trying to highlight it(row) with a different color. Tried if else condition with wc -l . but it didn't work. Below is my script . Please correct the script where i am doing wrong. Thanks in advance


Code:
#!/bin/sh
(
echo "To: MyMail@domain.com"
echo "Subject: Test HTML"
echo "Content-Type: text/html"
echo
echo "<html> <font face='verdana' size='7' >"
echo "<table border='1' width='100%' bgcolor='#DDDDDD' >" ;
while read INPUT ; 
do
b=$? echo  "$line"  | egrep "Failed|Absent" | wc -l
if [[ $b==0 ]]
then
 echo "<tr><td >${INPUT//,/</td><td>}</td></tr>"
else
 echo "<tr><td bgcolor='red' >${INPUT//,/</td><td bgcolor='red'>}</td></tr>"
fi ; done < file.csv ; echo "</table>" 
echo "</font></html>"
) | /usr/sbin/sendmail -t

Removing if else part , works fine and which completes my 1st part.

Code:
b=$? echo  "$line"  | egrep "Failed|Absent" | wc -l
if [[ $b==0 ]]
then
  



Quote:



    
    
echo "<tr><td >${INPUT//,/</td><td>}</td></tr>"

    




else
 echo "<tr><td bgcolor='red' >${INPUT//,/</td><td bgcolor='red'>}</td></tr>"
fi

Sample of file.csv

Code:
Student1,Subject1,Passed,2013-04-27,18:00:00
Student2,Subject2,Failed,2013-04-27,18:00:00
Student3,Subject3,Absent,2013-04-27,18:00:00
Student4,Subject4,In Progress,2013-04-27,18:00:00
Student5,Subject5,Failed,2013-04-27,18:00:00

LEARN ABOUT FREEBSD

forward

FORWARD(5)						      BSD File Formats Manual							FORWARD(5)

NAME

     forward -- mail forwarding instructions

DESCRIPTION

     The .forward file contains a list of mail addresses or programs that the user's mail should be redirected to.  If the file is not present,
     then no mail forwarding will be done.  Mail may also be forwarded as the standard input to a program by prefixing the line with the normal
     shell pipe symbol (|).  If arguments are to be passed to the command, then the entire line should be enclosed in quotes.  For security rea-
     sons, the .forward file must be owned by the user the mail is being sent to, or by root, and the user's shell must be listed in /etc/shells.

     For example, if a .forward file contained the following lines:

	   nobody@FreeBSD.org
	   "|/usr/bin/vacation nobody"

     Mail would be forwarded to <nobody@FreeBSD.org> and to the program /usr/bin/vacation with the single argument nobody.

     If a local user address is prefixed with a backslash character, mail is delivered directly to the user's mail spool file, bypassing further
     redirection.

     For example, if user chris had a .forward file containing the following lines:

	   chris@otherhost
	   chris

     One copy of mail would be forwarded to chris@otherhost and another copy would be retained as mail for local user chris.

FILES

     $HOME/.forward  The user's forwarding instructions.
