I have a program that is run on numerous AIX servers, that will collect information and then compare it to the previous day’s info. It will then email a list of any differences.

I am running into an issue where a new line will not always print after certain statements. It appears to be an issue with certain variables that are presented in these print statements. The strange thing is if I take the program through debug and view the array it shows that each statement is on a new line. The log prints correctly, but the email does not. Code: 

$message = "A difference in /opt/local/bin has been noted: $opt_local_
+bin{$file}{'new'}{'file'} is now available\n";
push @messages, $message;

then I will present them in a single variable and email them: 
$message = join('',@messages);
$subject = "CM Audit Daily Changes Notification";
&mail_admin($subject,$message);

[download]
The result I get from this is, where *NEWLINE* is the next difference the program finds:
A difference in /opt/local/bin has been noted: clean_oratab is no longer available *NEWLINE*A change in /etc/hosts has been detected. 10.40.250.3 r2dmn1 # regatta 2 domain 1 switch is no longer available

If I join with a new line ($message = join('\n',@messages);) I get:
A difference in /opt/local/bin has been noted: clean_oratab is no longer available

A change in /etc/hosts has been detected. 10.40.250.3 r2dmn1 # regatta 2 domain 1 switch is no longer available

But I do not want the whitespace between the lines.

If I use ‘’ between the variable and end of the line it works, but it prints the ‘’:

$message = "A difference in /opt/local/bin has been noted: ‘$opt_local
+_bin{$file}{'new'}{'file'} is now available’\n";
push @messages, $message;

gives the following result:

A difference in /opt/local/bin has been noted: ‘clean_oratab is no longer available’
A change in /etc/hosts has been detected. 10.40.250.3 r2dmn1 # regatta 2 domain 1 switch is no longer available

Obviously it is something in the variable output on certain lines. But again it only affects the emailed results, not anything I can see in debug or the log files which is an exact copy of what is sent to the email program.

Any ideas before I give up?
