I'm kind of stuck with a problem. (Apart from the obvious) Here is part of the flow and the list generation: [{"id":"1deb29d5.dfb98e","type":"ui_button","z":"a3bd09a.b852978","name":"Generate reboot history list","group":"9630e6fb.2f4208","order":1,"width":"4","height":"1","passthru":false,"label…

You can do tail -n16 file | tac

It would be easier if you shared an example of the data as well. It isn't really feasible for us to paste in everyone's code. Without looking at the data, I'm rather guessing but I would normally do this in Javascript by splitting the text into an array then sorting the array.

Sorry. Example file: 2019-7-16 22:10:12 Tue Jul 16 2019 22:10:12 GMT+1000 (AEST) >> Backup << 2019-7-17 14:15:40 Wed Jul 17 2019 14:15:40 GMT+1000 (AEST) >> Backup << 2019-7-17 17:45:48 Wed Jul 17 2019 17:45:48 GMT+1000 (AEST) >> Backup << 2019-7-17 20:40:33 Wed Jul 17 2019 20:40:33 GMT+1000 (A…

No problem. Hmm, bit of a problem there. The dates in that log are not sortable. They need to have leading zero's in the month and date so that they can be sorted correctly. Thankfully though, JavaScript as an array reverse function: [image] Array.prototype.reverse() The reverse() metho…

Thanks. Ok, bit more information for you. I get that the names in the file are confusing for sorting. It isn't I want to sort them. That isn't needed. The lines are added in time order to the file. I tried it with tac rather than cat and though it works...... Because the list on the screen…

With a bit of messing around I could use tail -n16 to get what I want. Given the list size is 16 lines. But that has the downside that I can't reverse the output like with tac. Still thinking. ( @dceejay ) What was the edit? Not too worried because looking I can't seem to see what was edited. B…

Ah! Silly me! Yes, thanks. Shall try it now. Didn't think of that. Bad news. For reasons unknown, I don't get an output from that. Running it from the CLI, it works. But putting that command into the exec node and pressing the button. Nothing. I think that is because (after a bit of dig…

Works fine, are you using an absolute path ? [08]

Yes. I shall try again shortly. (I'm looking at Bart's new node just now) vcgen. Looks interesting/handy. When I wasn't getting an output I tried it from the CLI and it seemed to work. I got/saw a list. But then when I went back to the CLI, I saw it hadn't exited. Weird. Standby for update…

That being I did: tail -n16 | tac (filename) rather than tail -n16 (filename) | tac yeah? Silly me. Thanks.

Look again at the command@bakman2 suggested and look at what you have used. When something doesn't work it is always worth checking for simple errors first.
