Mail sent from variable is not aligned in shell script
Hi Folks
Scenario,
Compared two values in two different files, if file1 value is greater than the value of file2 it trigger mail,
I tried this,
Code:
echo ${usep[@]};
echo ${usep1[@]};
for i in ${!usep[@]}; do
if [ ${usep[$i]} -gt 80 ]; then
if [ ${usep[$i]} -gt ${usep1[$i]} ]; then
tmp=$(echo "Running out of space \" ${usep[$i]}\" on $(hostname) as on $(date)");
alertlist="$tmp";
echo $alertlist;
echo "$alertlist" | mail -s "$ORACLE_SID ALERT: Running out of space" $maillist;
fi
fi
done
The issue is,
when I try
Code:
alertlist+="$tmp";
Running out of space "/u01 (99%)"
Running out of space "/u01 (99%)" Running out of space "/u02 (96%)"
Running out of space "/u01 (99%)" Running out of space "/u02 (96%)" Running out of space "/u03 (90%)"
It append the values in variable, and sent the mail entirely in a single line.
Meanwhile when I try
Code:
alertlist="$tmp";
Running out of space "/u01 (99%)"
Running out of space "/u02 (96%)"
Running out of space "/u03 (90%)"
it looks good but it sent the mail for each mount point separately, which I receive individually 3 times.
I need to receive a mail which all mount point contain above 80 in single mail.
How can I do that?

postfix
POSTFIX(1) General Commands Manual POSTFIX(1)NAME
postfix - Postfix control program
SYNOPSIS
postfix [-c config_dir] [-D] [-v] command
DESCRIPTION
This command is reserved for the super-user. To submit mail, use the Postfix sendmail command.
The postfix command controls the operation of the Postfix mail system: start or stop the master daemon, do a health check, and other main-
tenance.
The postfix command sets up a standardized environment and runs the postfix-script shell script to do the actual work.
The following commands are implemented:
check Validate the Postfix mail system configuration. Warn about bad directory/file ownership or permissions, and create missing directo-
ries.
start Start the Postfix mail system. This also runs the configuration check described above.
stop Stop the Postfix mail system in an orderly fashion. Running processes are allowed to terminate at their earliest convenience.
Note: in order to refresh the Postfix mail system after a configuration change, do not use the start and stop commands in succes-
sion. Use the reload command instead.
abort Stop the Postfix mail system abruptly. Running processes are signaled to stop immediately.
flush Force delivery: attempt to deliver every message in the deferred mail queue. Normally, attempts to deliver delayed mail happen at
regular intervals, the interval doubling after each failed attempt.
reload Re-read configuration files. Running processes terminate at their earliest convenience.
The following options are implemented:
-c config_dir
Read the main.cf and master.cf configuration files in the named directory instead of the default configuration directory. Use this
to distinguish between multiple Postfix instances on the same host.
-D (with postfix start only)
Run each Postfix daemon under control of a debugger as specified via the debugger_command configuration parameter.
-v Enable verbose logging for debugging purposes. Multiple -v options make the software increasingly verbose.
ENVIRONMENT
The postfix command sets the following environment variables:
MAIL_CONFIG
Directory with Postfix configuration files.
MAIL_VERBOSE
This is set when the -v command-line option is present.
MAIL_DEBUG
This is set when the -D command-line option is present.

command_directory
Directory with Postfix administrative commands.
daemon_directory
Directory with Postfix daemon programs.
config_directory
Directory with Postfix configuration files and with administrative shell scripts.
queue_directory
The directory with Postfix queue files, with local inter-process communication endpoints, and with files needed for daemon programs
that run in the optional chrooted environment.
mail_owner
The owner of Postfix queue files and of most Postfix processes.
setgid_group
The group for mail submission and queue management commands.
sendmail_path
The full pathname for the Postfix sendmail command.
newaliases_path
The full pathname for the Postfix newaliases command.
mailq_path
The full pathname for the Postfix mailq command.
manpage_directory
The directory for the Postfix on-line manual pages.
sample_directory

readme_directory
The directory for the Postfix README files.
Other configuration parameters
