More Details

-config
Allows users to change their configuration information. This includes user & team names (reflected in the stats), whether or not to ask before a network connection is made to fetch/send work, set up proxy servers, preferred work unit type (Folding/Genome), process priority, CPU usage requested (5-100%), whether or not to use assembly loops, whether or not to use deadline information, and Machine ID changes.

-configonly
Same as above, but quit following configuration instead of beginning work.
Applicable to client ver. 4.0 only

-delete x
Delete item #x from work queue. This option should only be used if there is a serious error with the current unit that the client does not automatically recover from (e.g. crash-inducing). This should not normally happen, and if it does, we would be grateful if you could send us the FAHlog.txt file from the unit that causes the error.

-license
Displays the end-user license agreement
Applicable to client ver. 4.0 only

-queueinfo
Get information on queued work units. Includes for each unit the status (READY/FINISHED/EMPTY), unit type (Folding/Genome), originating server, and date when the unit was received (local time in GMT), as well as deadline if the server sent that information.

-send x
Send result #x back to server. Exits after trying to send unit (successfully or unsuccessfully). Use "-send all" to send all results outstanding. If unit x is not a completed work unit then the client exits without doing anything.

-verbosity x
Sets the output level, from 1 to 9 (max). The default is 3. This option should be used if the user wishes to see more detailed client output, particularly useful if there is a problem which needs to be reported to the F@H client development team.

-oneunit
Instructs the client to quit following the completion of one work unit.
Applicable to client ver. 4.0 and up only

-forceasm
Instructs the core to use SSE/3DNow assembly instructions if possible, even if it has previously made the determination that the machine may not be handling this well.

-forceSSE
On machines with an AMD processor, Core_78 gives priority to 3DNow over SSE -- this overrides that.
Applicable to client ver. 4.0 only

Note: As noted by Sunny See Profile The -forceSSE flag was added to a version 3 client (and version 4 client) due to problems with some AMDs and GROMACs. Since that problem (lockups with some GROMACs WUs) has been resolved by cooperation between AMD and PandeGroup, the -forceSSE switch is no longer needed. It is not recognized starting with the Version 5.00 client.

-advmethods

The -advmethods flag will allow you to download the latest beta test cores and work units. This also does mean that you agree that if it crashes and causes you grief you won't complain about it, but you will report the issue to Stanford... They want to know. So, it's a little risky but the choice is up to you and you get to test things for Stanford. I only recommend you do this if you have more than one system as things do sometimes go awry.

-local
Use configuration files from local directory. This option has no meaning on Linux, but is vital on Windows and Macintosh for running multiple clients on a machine. It instructs the client to read its config information from the client.cfg file in the current directory rather than, on Windows, from the installation directory specified in the registry, or, on Macintosh, the Library/Folding@home directory. Information such as the user name, team name, proxy information, machine ID are maintained in the client.cfg file. The flag ensures that work does not conflict. Use "-local" only if you are planning on running more than one instance of Folding@Home on the same machine (this is only useful if you are running on a multi-processor machine). Create as many directories as there are processors on the machine, copy the exe files and client.cfg file into each of these directories, run "FAH3Console -local -config" on each and specify unique machine IDs for each directory (under the Advanced Settings option). From then onwards you may run each copy by switching to its directory and running with the -local flag.

Note
You can only run one instance of the SS or GUI per system. This means that if you want to run other instances at the same time(a dually for example) then you have to run the Console(text) version for the second client using the -local flag.

-help
Print out the command line flags available and then exit.
Applicable to client ver. 4.0 only

Linux Specific
-freeBSD
For use by those wishing to use the Linux client on a machine running FreeBSD. See our FAQ for details on how to do this, but with this flag, all Cores downloaded will automatically be branded as being a Linux executable.
Applicable to client ver. 4.0 only

Windows Specific
The below options are accepted but ignored by the clients for operating systems other than Microsoft Windows.

-pause
Pause after finishing and trying to send current unit. Allows a user to shut down after finishing a unit, by pressing Ctrl-C, without then getting new work to process. This is recommended if you are planning on shutting down your machine for a long time (e.g. for a vacation), or are planning to un/re-install F@H after finishing the currently processing work unit.

-service
Run in service mode (for programs such as firedaemon). This prevents the client from exiting when it detects the current user is logging out. If this option is used when the client is not run as a service then it will run normally, but will not shut down automatically if the user logs out, and a "Wait for program to close." dialog box will be displayed.

Additional details are available here and here.
