NAME

       doveadm-batch - Execute multiple commands for multiple users

SYNOPSIS

       doveadm [-Dv] batch [-S socket_path] -A sep command sep command [...]
       doveadm [-Dv] batch [-S socket_path] -u usermask sep command sep command [...]

DESCRIPTION

       The  command  doveadm  batch  is  used  to execute multiple doveadm(1) commands sequentially for multiple
       users.  This is primarily an optimization 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 them.

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

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -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   iterate_query   setting   in
              /etc/dovecot/dovecot-sql.conf.ext  matches  your  database  layout.   When  using  the LDAP userdb
              module, make sure that the iterate_attrs  and  iterate_filter  settings  in  /etc/dovecot/dovecot-
              ldap.conf.ext  match  your  LDAP  schema.  Otherwise doveadm(1) will be unable to iterate over all
              users.

       -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
              *@example.org).
              When neither the -A option nor -u user was specified,  the  command  will  be  executed  with  the
              environment of the currently logged in user.

ARGUMENTS

       command
              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.

EXAMPLE

       In this example we move seen mails, older than one month, for all example.net 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 primary storage.

       doveadm batch -u \*@example.net : altmove seen savedbefore 30d : purge
