       doveadm-batch - Execute multiple commands for multiple users


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


       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

       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


       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

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

       -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 -u user was specified, the command will be executed
              with the environment of the currently logged in user.


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

       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 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 \* : altmove seen savedbefore 30d : purge
