Re: Bash parsing file attributes like metadata

Thanks.

Yes, the toilets here can be dangerous - red-backs on the toilet seat, etc.

And here is is coming on summer and it is going to be a bit of a hot one. Although others say it is going to be wet.

But the new few days the temperature is going to be like 40 degrees Celsius.

Re: Bash parsing file attributes like metadata

Again: Thanks. I will not be able to test this for another week and at a place where they have only just discovered electricity. (Sorry. Oz humour. But it is out the back of no where.) :D The RasPie won't have internet connectivity. Though I fear I will have to hotspot it to get some parts working.

Re: Bash parsing file attributes like metadata

Wow! Thanks. That is good. Alas, there are a few "multi-artist" albums. However, there are also a lot of single-artist albums too. I'll play with it and see if it can help me. They were using an old machine - XP even! - but it is/was getting old and a bit unreliable. Alas XP is bound to 2T...

Bash parsing file attributes like metadata

I hope this is the better place to ask. Someone has a lot of MP3 files all stuck in one directory rather than via Album title. There are (obviously) no conflicts with names, but it is not nice. The metadata is there. Is there a way bash (or anything else) could parse the metadata, create a directory...

Re: Which book to buy?

Thanks.

I may need to follow that up a bit more.

Just sometimes a physical book is good as I can have it open at ..... page `X` while looking at the screen and studying what is going on and why.

Re: Which book to buy?

Thanks. I am asking because I recently had a whole lot of fun with the `ifup` and `ifdown` commands. Which are now deprecated. But thanks. That most commands are still there is somewhat consoling to me. Maybe I need something which can help me with the interrelationship of commands. (excusing the us...

Which book to buy?

Way before the RasPi existed and in the early days of internet, I had a dialup internet access and the server was Linux/Unix. To help me understand the commands I bought a Unix bible. But as the RasPi is a bit further down the track, I don't think that will be much good for me now. (And it is 25 yea...

Re: python - versions and what is what

Ok, I am stupid. That's a given. I can live with that. Don't really have a choice. But given what you said, there is still a big disconnect. Originally I did the whole things with pip . It worked, but didn't. I was advised to update to the v3 package. But before that happened, I wrote a script in Py...

python - versions and what is what

I am going mad with a recent display I bought. That aside, I have (finally - I hope) been shown the correct / latest python stuff for it. Where I was failing - supposedly - was I was using python 2.7 and not 3.7. Slight difference in the command to invoke the script. python3 rather than just python ...

Re: Connecting 20x4 LCD to raspberry pi for project.

Yes, I am using Python 2.7 The link from where I got it didn't say to use python3. Just `python`. I think I have tried using python3, and it errors. Though that may be because I downloaded the `2` version. So we are both on the same page: https://github.com/sparkfun/Qwiic_Py No mention of python3 th...

Continuing. So, although a command is there to adjust the back lighting..... It prints a message on the screen for you - which I don't want - and the colour changes through about 4 other ones before getting to ...... I don't know what. I set it to red. 150,0,0 as you can see in the command. Sorry he...

Slightly off topic, but it is under the realm of this quest. How do I know where that code installs itself?

Re: Connecting 20x4 LCD to raspberry pi for project.

Just FYI,

https://github.com/sparkfun/Qwiic_SerLCD_Py

Really helped me a lot.

Installed the QWIIC stuff and now it is working.
Well, 99%.

But that is good.

100% would be better, but I am tripping on some python stuff.

Connecting 20x4 LCD to raspberry pi for project.

I am wanting to make a project on a RasPi 3a board and use a 20x4 LCD screen. https://core-electronics.com.au/sparkfun-20x4-serlcd-black-on-rgb-3-3v.html This one.

Chrome from desktop and from CLI.

To keep things separate, this is a new problem for me. I have a RasPi with a LCD screen working. It boots, It seems to be working. I see the desktop and I created an icon for Chrome. If I double click the icon, Chromium loads but is bigger than the screen. (I'll get to that.) But at this point: It l...
