Is there a way to make finch tile it's 'windows'? I'm getting tired of constantly having to alt+m / r things around.

If not, is there another console-based solution like finch that supports tiling?

I'm trying to learn how to best write shell scripts. I have the following script for downloading YouTube videos as MP3 and injecting them with metadata + cover art:

code:

#!/bin/bash

yt-dlp \
    --windows-filenames \
    -x \
    --audio-format mp3 \
    --audio-quality 0 \
    --embed-metadata \
    --embed-thumbnail \
    --convert-thumbnails png \
    --exec-before-download "ffmpeg -i %(thumbnails.-1.filepath)q -vf crop=\"'if(gt(ih,iw),iw,ih)':'if(gt(iw,ih),ih,iw)'\" _%(thumbnails.-1.filepath)q" \
    --exec-before-download "rm %(thumbnails.-1.filepath)q" \
    --exec-before-download "mv _%(thumbnails.-1.filepath)q %(thumbnails.-1.filepath)q" \
    $1

$SHELL

I have it aliased in my .bashrc as this:

code:

alias music='exec /home/hovercastle/tools/scripts/music.sh'

When I try to chain multiple executions of this alias:

pre:

music url1 && music url2

it only runs the first one. What am I missing here?

Thanks for those replies, that is a huge help.

So, is yt-dlp returning an error? why do you have the $SHELL at the end there? etc

AFAICT yt-dlp is not returning any errors.
Adding $SHELL to the end is (supposedly) to ensure the script doesn't kill my shell and drop my ssh connection. At least that's what superuser says haha

Also you don't need a shell alias, ~/bin and ~/.local/bin are probably already in your path.

Where should I be putting scripts like this ideally?

Volguus posted:

Just make your script executable (chmod u+x) and remove the exec in the alias and you should be golden.

What does chmod u+x do? I normally just do chmod +x

Cool, thank you.

hifi posted:

If it only runs the first one then it's returning something other than zero; '&&' is a logical AND, so if the first one is false then there's no way the entire statement can be anything other than false.

How do I debug this? Is there an equivalent of try/catch for bash scripts?

Yeah. It works nicely with the exec and $SHELL removed. Thanks everyone.

That sounds like a weird idea, never seen that used before. If you have the link to that advice I'd be interested to see it.

I suspect the $SHELL is also the reason why your command chaining doesn't work, 'music url2' will only be executed after 'music url1' finishes, but it never does since it's running your new shell. If you run your script a bunch of times and then run 'pstree' you will probably see several nested music- and bash-processes.

Also, you may want to use 'music url1 ; music url2' instead. '&&' is used in a situation where you don't want the second command to execute if the first one wasn't succesful.

just to explain why that question is different from your situation - they want to run the script with a double-click and have it leave the terminal open. you are just trying to run the script from an already open terminal. in your case when the script finishes running you just get back to your current shell anyway.

Much appreciated, that makes sense.

Just as a side note to all the stuff you've got, you can use $@ so the script will read an arbitrary number of file names instead of having to chain together
code:
music url1; music url2
It would be
code:
music url1 url2 url<n>

Ahhh that's perfect, thanks.
