I have a little programming experience but am completely new to shell scripting.

I have several hundred mp3s which I want to split using mp3splt with the command

mp3splt -A XXX.txt XXX.mp3

I have run this command by hand in the past but now have a project where doing it by hand would be impractical due to the number of files. In my imagination it should be easy to write a script that searches a folder for all the mp3s that have a txt file of the same name and runs the above command on them.

My question just is this: Is there any obvious reason this would not work? If you (meaning: a person with experience in shell scripting) don´t see any such reason, I´d work my way through this tutorial to work out the rest. If, on the other hand, you say it is impossible, I can just stop and do it by hand.

Thanks in advance!

In case you are interested in my use case: I play irish music, which is based on short melodies played by heart. I want to learn these melodies using anki with audio files. For that, I need to have audio files with just one specific tune each.

    You’re correct about command substitutions, the $(...) part. I had initially thought putting it inside a sh would be clearer and avoid problems with substitutions. However, $0 is the name of the shell or the script. To fix this, we can put {} inside a variable, like this: file="{}". Then, we can use the variable $file for the rest of the command.

    I also think using for loops makes the command easier to read. But dealing with files that have spaces in their names can be really frustrating when you use for loops.
