Trying to figure out how to update HTML file

Mon Apr 16, 2018 2:33 am

I am new to Raspberry Pi. I am trying to find a way to save a certain part of a terminal output to a .html file to update a website.

Here's how the process would go.

User: Runs command

Pi: Outputs
"lorem ipsum dolor set amet 456
a1b2c3a1b2c3 temp=27.61"

Pi: Saves "27.61" to index.html

Is this possible, if so how?
If not, how can we make it possible? ;)

Yes its possible to write the temp to a file.

but without knowing a lot more about your existing program and what else you need in your html file I can only give you a general example.

Code: Select all

import time

adc =  " The time is "

reporttime = (time.strftime("%H:%M:%S"))

result = open("/home/pi/index.html","w")
result.write(adc + reporttime + "\n")

Please only ask questions in the forum I will not answer questions sent to me directly via PM

Code: Select all

<command> | tail -n 1 | cut -d = -f 2 > index.html
If that's not enough, you need to be more detail in what you want than:
