How to append the output continously from a script
Hi All,

Am using the below script to produce some statistics. Currently it send the results to a log file and sends the contents of the log to a mail ID.
Next time when it runs it erases the previous log and writes the latest output to the log file.

I want the output to be appended to the script and also the script should send email only with the latest result.

Please help..

Here is the script

. $HOME/.profile
echo "****CDR and SDR Queue****" > mg_stat.log
gs_admin |grep ^Queue |awk '{print $1,$2,$3,$4}' >> mg_stat.log
gs_admin |grep ^cdr |awk '{print $1,"\t\t"$2,"\t\t"$3,"\t\t"$4}' >> mg_stat.log
gs_admin |grep ^sdr |awk '{print $1,"\t\t"$2,"\t\t"$3,"\t\t"$4}' >> mg_stat.log
echo "name state last op busy%" >> mg_stat.log
cross_stat -server|grep sdr|awk '{print $2,$7,$9,$10}' >> mg_stat.log
cross_stat -server|grep cdr|awk '{print $2,$7,$9,$10}' >> mg_stat.log
echo "" >> mg_stat.log
echo "****CPU Usage****" >> mg_stat.log
uptime >> mg_stat.log
mailx -s "MG Stat" n.appandairajan@rci.rogers.com< /home/psms/mg_stat.log

doveadm-log

DOVEADM-LOG(1)							      Dovecot							    DOVEADM-LOG(1)

NAME

       doveadm-log - Locate, test or reopen Dovecot's log files

SYNOPSIS

       doveadm [-Dv] log errors [-s min_timestamp]
       doveadm [-Dv] log find [directory]
       doveadm [-Dv] log reopen
       doveadm [-Dv] log test

DESCRIPTION

       The  doveadm  log commands are used to locate and reopen the log files of dovecot(1).  It's also possible to test the configured targets of
       the *log_path settings.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -v     Enables verbosity, including progress counter.

COMMANDS

   log errors
       doveadm log errors [-s min_timestamp]

       The log errors command is used to show the last	- up to 1,000 - errors and warnings.  If no output is generated, no errors  have  occurred
       since the last start.

       -s min_timestamp
	      An  integer  value, representing seconds since the epoch - also known as Unix timestamp.	When a min_timestamp was given, doveadm(1)
	      will only show errors occurred since that point in time.

   log find
       doveadm log find [directory]

       The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages.	 If  dovecot(1)  logs  its
       messages  through  syslogd(8)  and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log
       files.

   log reopen
       doveadm log reopen

       This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings.  These settings
       are configured in /etc/dovecot/conf.d/10-logging.conf.
       This is for example useful after manually rotating the log files.

   log test
       doveadm log test

       This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files.  The used prior-
       ities are: debug, info, warning, error and fatal.

EXAMPLE

       This example shows how to locate the log files used by dovecot(1).

       doveadm log find
       Looking for log files from /var/log
       Debug: /var/log/dovecot.debug
       Info: /var/log/mail.log
       Warning: /var/log/mail.log
       Error: /var/log/mail.log
       Fatal: /var/log/mail.log

REPORTING BUGS

       Report bugs, including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>.  Information about reporting bugs	is  avail-
       able at: http://dovecot.org/bugreport.html
