       vfstest - tool for testing samba VFS modules

       vfstest [-d debuglevel] [-c command] [-l logdir] [-h]

       This tool is part of the samba(7) suite.

       vfstest is a small command line utility that has the ability to test
       dso samba VFS modules. It gives the user the ability to call the
       various VFS functions manually and supports cascaded VFS modules.

           Execute the specified (semicolon-separated) commands. See below for
           the commands that are available.

           Print a summary of command line options.

           File name for log/debug files. The extension '.client' will be
           appended. The log file is never removed by the client.

           level is an integer from 0 to 10. The default value if this
           parameter is not specified is 0.

           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.

           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.

           Note that specifying this parameter here will override the log
           level parameter in the smb.conf file.

           Prints the program version number.

       -s|--configfile=<configuration file>
           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.

           Base directory name for log/debug files. The extension ".progname"
           will be appended (e.g. log.smbclient, log.smbd, etc...). The log
           file is never removed by the client.

           Set the smb.conf(5) option "<name>" to value "<value>" from the
           command line. This overrides compiled-in defaults and options read
           from the configuration file.
