     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 (colon-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

         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 blue]log level] parameter in the smb.conf file.

         Prints the program version number.

     This man page is correct for version 3 of the Samba suite.

     The original Samba software and related utilities were
     created by Andrew Tridgell. Samba is now developed by the
     Samba Team as an Open Source project similar to the way the
     Linux kernel is developed.

     The vfstest man page was written by Jelmer Vernooij.
