.SH DESCRIPTION
The command
.B doveadm batch
is used to execute multiple
.BR doveadm (1)
.IR command s
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.
.PP
In the first form
.BR doveadm (1)
will loop over all users, defined in the configured
.IR user_db (s),
and execute the sequence of
.IR command s
for each of them.
.PP
In the second form
.BR doveadm (1)
will loop over all users, listed in the given
.IR file .
.PP
In the third form the
.IR command s
will be executed for each user matching the given
.IR usermask .

.SH EXAMPLE
In this example we move seen mails, older than one month, for all
example.net users to the alternative storage under /nfsmount:
.br
.nf
mail_location = mdbox:~/mdbox:ALT=/nfsmount/%h/mdbox
.fi
The second command will remove messages with refcount=0 from the
primary storage.
