Hello hacker public radio fans, this is EEZ once again with another episode.
|
|
This one is going to be really short.
|
|
It's just in response to Dave Morris' recent episode that I came out today, which is
|
|
Wednesday the 26th of February 2018 and it's about this little bash script that he wrote.
|
|
I say little but it is quite it's fully featured and well documented and has really good
|
|
best practices on how to write a bash script. But anyway I wouldn't expect anything else from Dave.
|
|
But what I wanted to talk about today just really briefly is how I just use the script
|
|
in a couple of minutes after inspecting it and looking out it worked.
|
|
I tried it out and I'm like oh that's pretty cool and I noticed what I had plugged in in my
|
|
house right now out of the six or seven that I own. I only have four plugged in and three of them
|
|
were Raspberry Pi 3's one is Raspberry Pi 2 and the three Raspberry Pi 3's they all worked with
|
|
the command just fine. But the Raspberry Pi 2 it's my oldest one that I still am using and I've
|
|
messed around with a lot so I don't know if I either deleted the VC GN-G-N-C-M-D command which is
|
|
the little utility that goes on the pies as a way to if you look in the script that he made it's
|
|
the real workers horse of the script it's the thing that is looking at all the able to look at all the
|
|
different pieces of information on the device and output them and for whatever reason I when I
|
|
ran the command on one of my on the Raspberry Pi 2 it said command not found I found a an article
|
|
about it and the other thing that's a little weird is I it's the only one that is running
|
|
Raspbian the other three are running of 1 2 6 0 4 but after looking around on line for a little bit
|
|
I found a form a Raspberry Pi form about what to do if it's not installed and
|
|
and I'm going to put a link to that in the in the show notes as well as the link inside the link
|
|
which basically what it says to do is oh here there's a GitHub repo where you can download
|
|
the source for this this program and then build it on the pie or you can build it off the
|
|
pie and cross compile which I didn't feel like knowing so I just record just went right onto
|
|
the pie and it doesn't matter if it takes a half hour I can just let it run and come back later
|
|
and I don't know how long it took because like I said I just let it run it came back later but
|
|
but yeah you just have to go and and get pull it and then CD into the directory and build it
|
|
and make sure you have CMake installed but yeah once once I did that I said well let me think
|
|
about this a little bit I can either there's a few ways I like to automate tools like this one of
|
|
them is using Ansible and I think I might have talked about Ansible before but it's a tool developed
|
|
by I think now it's developed by right now I don't know if it originally was and it's a way to
|
|
to do automation and it's it's agentless so unlike some other applications it's agentless
|
|
and on and you don't need to anything installed except for SSH and I'll use Fabric which is
|
|
for for similar reason because all you need is SSH but in the meantime before I started to do
|
|
anything crazy or anything fancy I just made a simple for loop and I have I know the host names
|
|
are those for Raspberry Pi so I just said in pseudo code it goes like this for Pi in this list of
|
|
Raspberry Pi host names I want to cat the what Pi file and then I want to pipe the output of the cat
|
|
which is you know the the details of file into SSH and then do a bash do a bash command of
|
|
the standard out which is that file name on every one of those on every one of those host so what
|
|
ends up happening is one by one I get a screen full of information about that Raspberry Pi
|
|
and if I wanted to I could redirect the output of that and so a text file just so I'll have it
|
|
so that's what I did all right now I'll also put that one liner in my show notes
|
|
just to show how I used it and but I think this is what hacker public radio is all about
|
|
it's about a community of people who like to tinker and mess around with things sharing their
|
|
experiences and then every once in a while you find one of those gems that really connects with
|
|
you and you you try it out yourself and it works for you and it makes you smile sometimes it can
|
|
be something simple and just get something accomplished for a personal project sometimes
|
|
it can at least for me turn into a big idea that I have for my company or way to I can market
|
|
my my services in a way that I didn't have before but a lot of times like I said it's just
|
|
you know doing something fun and and learning more about hobbies that interest you
|
|
so that's it for this episode stay tuned for more episodes of hacker public radio once again
|
|
I invite all listeners to record this an episode just like I am right now one note about this
|
|
recording if it sounds different than previous recordings I'm doing this on purpose to show how
|
|
easy it is I just right now looked for a random video audio recorder on my phone Android phone
|
|
installed it and started recording this episode and so within five minutes you can start
|
|
recording an episode for hacker public radio that's all easy it is now I just have to go and save
|
|
this file I'll probably move it to my computer and then just go to hacker public radio but I only
|
|
think I need to do that I'm pretty sure if I just went to hacker public radios website on my phone
|
|
I should be able to just do it straight from there actually I'm going to try that that will be my
|
|
mission for today I want to do this all just from my phone to show how easy it is so thank you once
