.SH "DESCRIPTION"
.P
The \fBdoveadm fs\fR \fIcommands\fR are used to abstractly interact with the storage driver defined in the Dovecot configuration. It allows access to the mailbox structure without needing to know details of how the storage driver is designed.
.P
\fIconfig-filter-name\fR
.RS 0
.RS 4
.P
Filter name to use when looking up the fs settings. For example \fImail_attachments\fR, \fIobox\fR, \fImetacache\fR, \fIfts/dovecot\fR. It's also possible to use an empty filter name and specify the fs settings using the \fB-o\fR parameter.

.SH "OPTIONS"
.P
\fB-A\fR
.RS 0
.RS 4
.P
If the \fB-A\fR option is present, the \fIcommand\fR will be performed for all users. Using this option in combination with system users from \fBuserdb { driver = passwd }\fR is not recommended, because it contains also users with a lower UID than the one configured with the \fBfirst_valid_uid\fR setting.
.P
When the SQL userdb module is used, make sure that the \fBuserdb_sql_iterate_query\fR setting setting matches your database layout.
.P
When using the LDAP userdb module, make sure that the \fBuserdb_fields\fR setting and \fBuserdb_ldap_iterate_fields\fR setting settings match your LDAP schema. Otherwise doveadm(1) will be unable to iterate over all users.

.P
\fB-F\fR \fIfile\fR
.RS 0
.RS 4
.P
Execute the \fIcommand\fR for all the users in the \fIfile\fR. This is similar to the \fB-A\fR option, but instead of getting the list of users from the userdb, they are read from the given \fIfile\fR. The \fIfile\fR contains one username per line.

.P
\fB-S\fR \fIsocket_path\fR
.RS 0

.P
The option's argument is either an absolute path to a local UNIX domain socket, or a hostname and port (\fIhostname\fR:\fIport\fR), in order to connect a remote host via a TCP socket.
.P
This allows an administrator to execute doveadm(1) mail commands through the given socket.
