Simple Command Line Download Speed Test

I got a server that started to have a bad network connection. To help debugging this I needed to collect some data, e.g. of running a download test every 5 minutes. A quick search revealed nothing so I found a simple way to do that with curl and Google Drive. 1. Google Drive Form I set up a simple Google Drive form that accepts two text values: Next I need to find out the HTML form field names of these two fields. This takes a little bit of digging.   There is always a label  attached to each input  field. They are connected via the for  attribute of the label. With this information I can now construct a simple curl script. 2. CURL script to collect some data and post I want curl to try to download a URL and record the download speed. The -w , -y and -Y options come in handy for this purpose: -w lets me output only the information I really care about (the speed of the download in Bytes per second) -y gives a timeout after which curl will abort the download -Y
