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] -F file 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 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.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -o setting=value
              Overrides  the  configuration  setting  from /etc/dovecot/dovecot.conf and from the
              userdb with the given value.  In order to override multiple settings, the -o option
              may be specified 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  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.

       -F file
              Execute the command for all the users in the file.   This  is  similar  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 *@example.org).
              When neither the -A option, nor the -F file option, nor the -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
