ethminer 是一個挖 Ethereum (ETH) 的軟體，只要是同屬 Ethash 的競爭幣都可以使用。此軟體最大的特色是沒有開發者抽成，當然也不需要自己去編譯了。
在 ethminer 0.14.0 的新版本中，已準備棄用多個與礦池有關的參數，目前舊的參數還是可以使用但會顯示警告，並在未來的版本將會移除，以下的參數會被一行的 -P 所取代。
-F, --farm, -FF, -SF, -FS, --farm-failover, --stratum-failover, -S, --stratum, -O, --userpass, -SP, --stratum-protocol, --stratum-ssl, -FO, --failover-userpass, -u, --user, -p, --pass, -o, --port, -fu, --failover-user, -fp, --failover-pass, -fo, --failover-port

-RH ^
--farm-recheck 200 ^
-G
每行最後的 " ^" 是為了斷行，這樣看得比較清楚。若是 Linux 及 Mac 的使用者請使用 " \" 。
其中要特別說明的是 stratum1+tcp:// ，如果是 getwork 就要填 http ，如果是 stratum 則可以填以下任一個
stratum+ssl
stratum+tcp
stratum+tls
stratum+tls12
stratum1+ssl
stratum1+tcp
stratum1+tls
stratum1+tls12
stratum2+ssl
stratum2+tcp
stratum2+tls
stratum2+tls12
你可以發現上面那一大坨有些只差在數字，前者對應 -SP 和 --stratum-protocol ，後者則對應 --stratum-ssl ，不過最常用的還是 tcp 和 ssl 啦。
最後將指令存成 .bat (Windows) 與 .sh (Linux Mac) 再執行就可以開挖囉。

附上官方指令參數說明
Usage ethminer [OPTIONS] Options: Work farming mode: -F,--farm <url> (deprecated) Put into mining farm mode with the work server at URL (default: http://127.0.0.1:8545) -FF,-FO, --farm-failover, --stratum-failover <url> (deprecated) Failover getwork/stratum URL (default: disabled) --farm-retries <n> Number of retries until switch to failover (default: 3) -S, --stratum <host:port> (deprecated) Put into stratum mode with the stratum server at host:port -SF, --stratum-failover <host:port> (deprecated) Failover stratum server at host:port -O, --userpass <username.workername:password> (deprecated) Stratum login credentials -FO, --failover-userpass <username.workername:password> (deprecated) Failover stratum login credentials (optional, will use normal credentials when omitted) --work-timeout <n> reconnect/failover after n seconds of working on the same (stratum) job. Defaults to 180. Don't set lower than max. avg. block time --stratum-ssl [<n>] (deprecated) Use encryption to connect to stratum server. 0: Force TLS1.2 (default) 1: Allow any TLS version 2: Allow self-signed or invalid certs and any TLS version -SP, --stratum-protocol <n> (deprecated) Choose which stratum protocol to use: 0: official stratum spec: ethpool, ethermine, coinotron, mph, nanopool (default) 1: eth-proxy compatible: dwarfpool, f2pool, nanopool (required for hashrate reporting to work with nanopool) 2: EthereumStratum/1.0.0: nicehash -RH, --report-hashrate Report current hashrate to pool (please only enable on pools supporting this) -HWMON [<n>], Displays gpu temp, fan percent and power usage. Note: In linux, the program uses sysfs, which may require running with root privileges. 0: Displays only temp and fan percent (default) 1: Also displays power usage --exit Stops the miner whenever an error is encountered -SE, --stratum-email <s> Email address used in eth-proxy (optional) --farm-recheck <n> Leave n ms between checks for changed work (default: 500). When using stratum, use a high value (i.e. 2000) to get more stable hashrate output -P URL Specify a pool URL. Can be used multiple times. The 1st for for the primary pool, and the 2nd for the failover pool. URL takes the form: scheme://user[:password]@hostname:port[/emailaddress]. for getwork use one of the following schemes: http for stratum use one of the following schemes: stratum+ssl stratum+tcp stratum+tls stratum+tls12 stratum1+ssl stratum1+tcp stratum1+tls stratum1+tls12 stratum2+ssl stratum2+tcp stratum2+tls stratum2+tls12 Example 1 : stratum+ssl://0x012345678901234567890234567890123.miner1@ethermine.org:5555 Example 2 : stratum1+tcp://0x012345678901234567890234567890123.miner1@nanopool.org:9999/john.doe@gmail.com Example 3 : stratum1+tcp://0x012345678901234567890234567890123@nanopool.org:9999/miner1/john.doe@gmail.com Benchmarking mode: -M [<n>],--benchmark [<n>] Benchmark for mining and exit; Optionally specify block number to benchmark against specific DAG. --benchmark-warmup <seconds> Set the duration of warmup for the benchmark tests (default: 3). --benchmark-trial <seconds> Set the duration for each trial for the benchmark tests (default: 3). --benchmark-trials <n> Set the number of benchmark trials to run (default: 5). Simulation mode: -Z [<n>],--simulation [<n>] Mining test mode. Used to validate kernel optimizations. Optionally specify block number. Mining configuration: -G,--opencl When mining use the GPU via OpenCL. -U,--cuda When mining use the GPU via CUDA. -X,--cuda-opencl Use OpenCL + CUDA in a system with mixed AMD/Nvidia cards. May require setting --opencl-platform 1 or 2. Use --list-devices option to check which platform is your AMD. --opencl-platform <n> When mining using -G/--opencl use OpenCL platform n (default: 0). --opencl-device <n> When mining using -G/--opencl use OpenCL device n (default: 0). --opencl-devices <0 1 ..n> Select which OpenCL devices to mine on. Default is to use all -t, --mining-threads <n> Limit number of CPU/GPU miners to n (default: use everything available on selected platform) --list-devices List the detected OpenCL/CUDA devices and exit. Should be combined with -G, -U, or -X flag --display-interval <n> Set mining stats display interval in seconds. (default: every 5 seconds) -L, --dag-load-mode <mode> DAG generation mode. parallel - load DAG on all GPUs at the same time (default) sequential - load DAG on GPUs one after another. Use this when the miner crashes during DAG generation single <n> - generate DAG on device n, then copy to other devices OpenCL configuration: --cl-kernel <n> Use a different OpenCL kernel (default: use stable kernel) 0: stable kernel 1: experimental kernel --cl-local-work Set the OpenCL local work size. Default is 128 --cl-global-work Set the OpenCL global work size as a multiple of the local work size. Default is 8192 * 128 --cl-parallel-hash <1 2 ..8> Define how many threads to associate per hash. Default=8 CUDA configuration: --cuda-block-size Set the CUDA block work size. Default is 128 --cuda-grid-size Set the CUDA grid size. Default is 8192 --cuda-streams Set the number of CUDA streams. Default is 2 --cuda-schedule <mode> Set the schedule mode for CUDA threads waiting for CUDA devices to finish work. Default is 'sync'. Possible values are: auto - Uses a heuristic based on the number of active CUDA contexts in the process C and the number of logical processors in the system P. If C > P, then yield else spin. spin - Instruct CUDA to actively spin when waiting for results from the device. yield - Instruct CUDA to yield its thread when waiting for results from the device. sync - Instruct CUDA to block the CPU thread on a synchronization primitive when waiting for the results from the device. --cuda-devices <0 1 ..n> Select which CUDA GPUs to mine on. Default is to use all --cuda-parallel-hash <1 2 ..8> Define how many hashes to calculate in a kernel, can be scaled to achieve better performance. Default=4 --cuda-noeval bypass host software re-evaluation of GPU solutions. This will trim some milliseconds off the time it takes to send a result to the pool. Use at your own risk! If GPU generates errored results they WILL be forwarded to the pool Not recommended at high overclock. API core configuration: --api-port Set the api port, the miner should listen to. Use 0 to disable. Default=0, use negative numbers to run in readonly mode. for example -3333. General Options: -v,--verbosity <0 - 9> Set the log verbosity from 0 to 9 (default: 5). Set to 9 for switch time logging. -V,--version Show the version and exit. -h,--help Show this help message and exit. Environment variables: NO_COLOR - set to any value to disable color output. Unset to re-enable color output.
