命令列下測ISP的網路速度 (SpeedTest For console)
說到要測ISP網路速度會想到的就是speedtest這個專門在測試的網站，選擇適合的伺服器就能測試它的上傳與下載的速度實在很不錯。不過，現在已經有人利用Python寫出命令列下的版本，程式名為speedtest-cli。
安裝
官網提供了幾種安裝方式
pip
pip install speedtest-cli
或
easy_install speedtest-cli
或
pip install git+https://github.com/sivel/speedtest-cli.git
wget
wget -O speedtest-cli https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py chmod +x speedtest-cli
curl
curl -o speedtest-cli https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py chmod +x speedtest-cli
在這我選擇wget的方式，下載後記得將屬性改成可執行的指令。
開始測試速度
直接執行speedtest-cli
danny:~$ ./speedtest-cli Retrieving speedtest.net configuration... Retrieving speedtest.net server list... Testing from CHTD, Chunghwa Telecom Co., Ltd. (xxx.xxx.218.xxx)... Selecting best server based on ping... Hosted by Taiwan Fixed Network (Taoyuan) [36.72 km]: 10.014 ms Testing download speed........................................ Download: 9.53 Mbit/s Testing upload speed.................................................. Upload: 3.38 Mbit/s danny:~$
上面能看出來整個測試的訊息與結果：

進階設定
安裝完成後執行speedtest-cli -h得到更細節的操作方式
$ speedtest-cli -h
usage: speedtest-cli [-h] [--share] [--simple] [--list] [--server SERVER]
[--mini MINI] [--source SOURCE] [--version]
Command line interface for testing internet bandwidth using speedtest.net.
--------------------------------------------------------------------------
https://github.com/sivel/speedtest-cli
optional arguments:
-h, --help show this help message and exit
--share Generate and provide a URL to the speedtest.net share
results image
--simple Suppress verbose output, only show basic information
--list Display a list of speedtest.net servers sorted by distance
--server SERVER Specify a server ID to test against
--mini MINI URL of the Speedtest Mini server
--source SOURCE Source IP address to bind to
--version Show the version number and exit
這裡我們可以指定server ID來選擇測試的伺服器，先執行伺服器列表指定將所有的伺服器列出：
speedtest-cli --list
之後就可以看到一堆伺服器的列表
941) Aeronet Broadband Corp (San Juan, Puerto Rico) [15144.11 km] 3807) HOTSPOTPR BROADBAND INTERNET (Bayamon, Puerto Rico) [15150.23 km] 3012) CLARO-PRT (Bayamon, Puerto Rico) [15150.23 km] 4122) Delvivi.net (Utuado, Puerto Rico) [15153.25 km] 2088) LibertyPR (Luquillo, Puerto Rico) [15158.67 km] 3712) LIME (Road Town, Virgin Islands) [15168.42 km] 2888) Innovative (Saint Thomas, Virgin Islands) [15175.24 km] 2884) Broadband VI (Saint Thomas, Virgin Islands) [15175.24 km] 2135) CLARO-PRT (Guaynabo, Puerto Rico) [15179.41 km] 3657) Open Mobile (Guaynabo, Puerto Rico) [15179.41 km] : : : 未完 :
因為太多伺服器位址，在這我已經將台灣伺服器整理出來如下：
2182) kbro Co., Ltd. (Hsinchu, Taiwan) 2590) Far EasTone Telecommunications Co., Ltd (Hsinchu, Taiwan) 2934) Far Eastone Telecommunications Co., Ltd. (Neihu, Taiwan) 2589) Far EasTone Telecommunications Co., Ltd (Taoyuan, Taiwan) 3921) Taiwan Fixed Network (Taoyuan, Taiwan) 4505) Chief Telecom (New Taipei, Taiwan) 2327) Far Eastone Telecommunications Co., Ltd. (Taipei, Taiwan) 2188) TFN Media Co., Ltd. (Taipei, Taiwan) 2181) kbro Co., Ltd. (Taipei, Taiwan) 2133) Taiwan Fixed Network (Taipei, Taiwan) 3967) Chief Telecom (Taipei, Taiwan) 2187) TFN Media Co., Ltd.

(Hsinying, Taiwan) 2592) Far EasTone Telecommunications Co., Ltd (Tainan, Taiwan) 4413) Chief Telecom (Tainan, Taiwan) 2594) Far EasTone Telecommunications Co., Ltd (Pingtung, Taiwan) 2190) kbro Co., Ltd.

最後我們再下指定伺服器的命令來針對某個伺服器測試ISP對它的速度：
speedtest-cli --server 2182
2181 為新竹的伺服器
2182) kbro Co., Ltd. (Hsinchu, Taiwan)
danny:~$ ./speedtest-cli --server 2182 Retrieving speedtest.net configuration... Retrieving speedtest.net server list... Testing from CHTD, Chunghwa Telecom Co., Ltd. (xxx.xxx.218.xxx)... Hosted by kbro Co., Ltd. (Hsinchu) : 10.888 ms Testing download speed........................................ Download: 6.17 Mbit/s Testing upload speed.................................................. Upload: 3.78 Mbit/s
如果你在測試時發現如下的問題：

表示可能speedtest-cli與SpeedTest網站在連線上超過重試次數，請再重新執行命令就能改善，最後再加碼測試一組：
speedtest-cli
danny:~$ ./speedtest-cli --server 2190 Retrieving speedtest.net configuration... Retrieving speedtest.net server list... Testing from CHTD, Chunghwa Telecom Co., Ltd. (xxx.xxx.218.xxx)...
