CyberSecurity part 13

So we are on part 13, well done and thank you to everyone who has stuck with this so far.

So today, I am going to link to three videos, which give more details on specific bash commands. Hopefully this will speed things up a little, there are probably better videos, so please feel free to search, watch and share alternative videos.

Ansi Weather

Getting weather information is really useful. What happens if you're at the command line in Linux? I found a really little application that can help

ansiweather

apt install ansiweather

ansiweather -l Plymouth, UK

Ansi Weather Output

So what else can we do with this

  1. Send the output to Mastodon with toot post

This is a two step process

  1. ansiweather -l Plymouth, UK > weather.txt
  2. toot post < weather.txt

Will send the weather info to Mastodon.

However this does not include any date info

We can fix this with

  1. date > weatherinfo.txt
  2. ansiweather -l Plymouth, UK >> weatherinfo.txt

then send the whole lot to Mastodon with

  1. toot post < weatherinfo.txt

So, if we put this in to a final shell script we need:-

#send weather info to Mastodon
# current date
date > weatherinfo.txt
# current weather
ansiweather -l Plymouth, UK >> weatherinfo.txt
#send to Mastodon
toot post < weatherinfo.txt
# done
echo done

I tried to get festival to speak the weather, it is not perfect but this sort of works, you will need to direct to weather.txt first.

festival —tts < weather.txt

Looking in to this further, the issue is the brackets etc, so this stackoverflow post

strips out the colour formatting

sed 's/\x1b[[^\x1b]*m//g' weatherinfo.txt

Therefore

sed 's/\x1b[[^\x1b]*m//g' weatherinfo.txt > weatherinfo2.txt

Sends the newly formatted text to weatherinfo2.txt

So running back through festival

festival —tts < weather.txt

Is perhaps a little better, but not perfect

So going back to what we wrote earlier to send to Mastodon, the new script

  1 #send weather info to Mastodon
  2 # current date
  3 date > weatherinfo.txt
  4 # current weather
  5 ansiweather -l Plymouth, UK >> weatherinfo.txt
  6 # clean up output with sed
  7 sed 's/\x1b\[[^\x1b]*m//g' weatherinfo.txt > weatherinfo2.txt
  8 #send to Mastodon
  9 toot post < weatherinfo2.txt
 10 # done
 11 echo done

Produces much nicer output. The top bottom part of this illustrates what was sent before we stripped out the colour formatting

However it still isn't perfect, as it removes part some of the wording, but it is hopefully getting there.
