.SH "OPTIONS"
.PP
\-p|\-\-persistent
.RS 4
Open the database as a persistent database\&. If this option is not specified, the database is opened as non\-persistent\&.
.RE
.PP
\-d|\-\-debuglevel=level
.RS 4
\fIlevel\fR
is an integer from 0 to 10\&. The default value if this parameter is not specified is 1\&.
.sp
The higher this value, the more detail will be logged to the log files about the activities of the server\&. At level 0, only critical errors and serious warnings will be logged\&. Level 1 is a reasonable level for day\-to\-day running \- it generates a small amount of information about operations carried out\&.
.sp
Levels above 1 will generate considerable amounts of log data, and should only be used when investigating a problem\&. Levels above 3 are designed for use only by developers and generate HUGE amounts of log data, most of which is extremely cryptic\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBlog level\fR\m[]
parameter in the
smb\&.conf
file\&.
.RE
.PP
\-V|\-\-version
.RS 4
Prints the program version number\&.
.RE
.PP
\-s|\-\-configfile=<configuration file>
.RS 4
The file specified contains the configuration details required by the server\&. The information in this file includes server\-specific information such as what printcap file to use, as well as descriptions of all the services that the server is to provide\&. See
smb\&.conf
for more information\&. The default configuration file name is determined at compile time\&.
.RE
.PP
\-l|\-\-log\-basename=logdirectory
.RS 4
Base directory name for log/debug files\&. The extension
\fB"\&.progname"\fR
will be appended (e\&.g\&. log\&.smbclient, log\&.smbd, etc\&.\&.\&.)\&. The log file is never removed by the client\&.
.RE
.PP
\-\-option=<name>=<value>
.RS 4
Set the
\fBsmb.conf\fR(5)
option "<name>" to value "<value>" from the command line\&. This overrides compiled\-in defaults and options read from the configuration file\&.
.RE
.PP
\-?|\-\-help
.RS 4
Print a summary of command line options\&.
.RE
.PP
\-\-usage
.RS 4
Display brief usage message\&.
