[SOLVED] A question about send mail in script

thomas2004ch · 10-28-2013, 04:13 AM

Hi,

I have a script as cronjob as follow:

Code:

#!/bin/bash

SUBJECT="This is a test"

result=$(find /var/log/jboss-apps/test -type f -size +10k)

#echo RESULT=$result

if [[ -z $result ]]; then
  echo NULL
else
  echo RESULT=$result
  $result | mail -s $SUBJECT my.name@mycom.com
fi

What I want to do is:
I will check if any file size greater than 10k every 10 min., assumed,.

But to my strange the email is send to the following addresse:

my.name@mycom.com; a@mycom.com; is@mycom.com; test@mycom.com;

Seems the SUBJECT is broken to as email addresses.

And the result is not send as contents.

Why?

Shouldn't that be:

Code:

echo "$result" | mail -s "$SUBJECT" my.name@mycom.com

Also mind the double quotes.

I also noticed the double quotes and change as follow:

Code:

...
RECEIVER="my.name@mycom.com"
...

if [[ -z $result ]]; then
  echo NULL
else
  echo RESULT=$result
  "$result" | mail -s "$SUBJECT" "$RECEIVER"
fi
...

Now the email is just sent to one email address "my.name@mycom.com". But I can't see the contents though it must be not NULL.

And as I run this script I got:

Code:

RESULT=/var/log/jboss-apps/test/server.log.2013-10-24
./check-file-size: line 17: /var/log/jboss-apps/test/server.log.2013-10-24: Permission denied
Null message body; hope that's ok

The line 17 is: "$result" | mail -s "$SUBJECT" "$RECEIVER"

OK let's try again

Code:

echo "$result" | mail -s "$SUBJECT" "$RECEIVER"

and not

Code:

"$result" | mail -s "$SUBJECT" "$RECEIVER"
