.SH DESCRIPTION
.B sgminer
is a multi-threaded multi-pool GPU miner with ATI GPU monitoring, (over)clocking and fanspeed support for scrypt-based cryptocurrency. It is based on cgminer by Con Kolivas (ckolivas), which is in turn based on cpuminer by Jeff Garzik (jgarzik).
.SH USAGE
.PP
The classic and best usage of sgminer is to load a json formatted config file which specifies all the options you need. This is done by:
.RS
\f(CWsgminer -c /etc/sgminer.conf
.RE
You can run sgminer without a config file by specifying pools and GPU specifics on the command line.
Single pool:
.RS
\f(CWsgminer -o http://pool:port -u username -p password
.RE
.PP
Multiple pools:
.RS
\f(CWsgminer -o http://pool1:port -u pool1username -p pool1password -o http://pool2:port -u pool2usernmae -p pool2password
.RE
.PP
Single pool with a standard http proxy, regular desktop:
.RS
\f(CWsgminer -o "http:proxy:port|http://pool:port" -u username -p password
.RE
.PP
Single pool with various GPU options specified:
.RS
\f(CWsgminer -o http://pool:port -u username -p password --auto-fan --auto-gpu --gpu-memclock 1400 --gpu-threads 1 --expiry 30
