Output from cron

As I've said before, the output from cron gets mailed to the owner of the process, or the person specified in the MAILTO variable, but what if you don't want that? If you want to mail the output to someone else, you can just pipe the output to the command mail.

e.g.

cmd | mail -s "Subject of mail" user

If you wish to mail the output to someone not located on the machine, in the above example, substitute user for the email address of the person who wishes to receive the output.

If you have a command that is run often, and you don't want to be emailed the output every time, you can redirect the output to a log file (or /dev/null, if you really don't want the output).

e.g.

cmd >> log.file

Notice we're using two > signs so that the output appends the log file and doesn't clobber previous output. The above example only redirects the standard output, not the standard error, if you want all output stored in the log file, this should do the trick:

cmd >> logfile 2>&1

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
