       doveadm-batch - Execute multiple	commands for multiple users

       mand [...]

       The  command  doveadm batch is used to execute multiple doveadm(1) com-
       mands sequentially for multiple users.  This is primarily an  optimiza-
       tion  where Dovecot can do all the mailbox operations for the same user
       at once,	instead	of having to go	through	the users multiple times.

       In the first form doveadm(1) will loop over all users, defined  in  the
       configured user_db(s), and execute the sequence of commands for each of

       In the second form doveadm(1) will loop over all	users, listed  in  the
       given file.

       In  the third form the commands will be executed	for each user matching
       the given usermask.

       Global doveadm(1) options:

       -D     Enables verbosity	and debug messages.

       -o setting=value
	      Overrides	the configuration  setting  from  /usr/local/etc/dove-
	      cot/dovecot.conf	and  from the userdb with the given value.  In
	      order to override	multiple settings, the -o option may be	speci-
	      fied multiple times.

       -v     Enables verbosity, including progress counter.

       Command specific	options:

       -A     If  the  -A option is present, the command will be performed for
	      all users.  Using	this option in combination with	 system	 users
	      from  userdb  { driver = passwd }	is not recommended, because it
	      contains also users with a lower UID  than  the  one  configured
	      with the first_valid_uid setting.

	      When  the	 SQL  userdb  module  is used make sure	that the iter-
	      ate_query	setting	in /usr/local/etc/dovecot/dovecot-sql.conf.ext
	      matches  your  database layout.  When using the LDAP userdb mod-
	      ule, make	sure that the iterate_attrs  and  iterate_filter  set-
	      tings in /usr/local/etc/dovecot/dovecot-ldap.conf.ext match your
	      LDAP schema.  Otherwise doveadm(1) will  be  unable  to  iterate
	      over all users.

       -F file
	      Execute the command for all the users in the file.  This is sim-
	      ilar to the -A option, but instead of getting the	list of	 users
	      from  the	 userdb,  they are read	from the given file.  The file
	      contains one username per	line.

       -S socket_path
	      The option's argument is either an absolute path to a local UNIX
	      domain  socket, or a hostname and	port (hostname:port), in order
	      to connect a remote host via a TCP socket.

	      This allows an administrator to execute doveadm(1) mail commands
	      through the given	socket.

       -u user/mask
	      Run  the command only for	the given user.	 It's also possible to
	      use '*' and '?' wildcards	(e.g. -u *
	      When neither the -A option, nor  the  -F file  option,  nor  the
	      -u user was specified, the command will be executed with the en-
	      vironment	of the currently logged	in user.

	      Any doveadm(1) command, with arguments and options -- except for
	      the -A, -S and -u	options.

       sep    A	 single	 character  used  as  command separator, e.g. ':'.  Be
	      careful, unquoted	characters, like ; or &, may be	interpreted by
	      your shell and doveadm(1)	will never see them.

       In this example we move seen mails, older than one month, for all exam- users to	the alternative	storage	under /nfsmount:
       mail_location = mdbox:~/mdbox:ALT=/nfsmount/%h/mdbox
       The second command will remove messages with refcount=0 from  the  pri-
       mary storage.

       doveadm batch -u	\* : altmove seen savedbefore 30d :	purge
