Removing Music/ from Output [Shell Script]

anon033 · 05-24-2019, 02:57 PM

I am writing a simple shell script to print out all of my music in ~/Music. I am wanting to do it using generic shell script (IE no bash specific things). I currently have this

Code:

cd ${HOME} && ls -R Music | sed 's/ //'

which outputs (get ready) all of this: https://privatebin.net/?7f4c76eb503a...0GtX5y21aq/AI=. I want to remove the Music/ that shows before each line and it showing all artist names at the very top of the output (I only need the parts where is shows artist/album/song). I can't figure out how though, can someone point me in the right direction?

I solved the first part, my syntax was wrong when I tried it before. This removed the /Music tid bit:

[code]
cd ${HOME} && ls -R Music | sed 's/ //' | sed 's/Music\///'

[\code]

ls -R lists the files recursively. That's why you're seeing the mp3 files.

If you only want artist folders, you can do:

Code:

ls $HOME/Music

This is assuming you don't have ls aliased to something like ls -la.

I mean I want to see output like:

Code:

骨架的/Skeleton:
baby.mp3
cold.mp3
foam.mp3
glowing.mp3
melting.mp3
microwave.mp3
orange.mp3
sewer.mp3
skeleton.mp3
sunset.mp3

but not parts like this

Code:

Music/骨架的:
Holograms
Skeleton

or this

Code:

Please post a dozen or so examples of the output of ls with no filtering.
That is, what is the input of the filtering you want to do?

You could try working with the tree command in that case.

Are you using BSD's ls, or GNU's? I'm not familiar with BSD, but what you're looking to do is possible with GNU's ls.

Code:

ls -RF1 Music | grep -v '/$' | tail -n+3 | sed 's!Music/!!'

Here is how it works:
-R means recurse. You seem to have a grasp of that, so I'll move on.
-F means "classify." This option tells ls to append an indicator (*/=>@|) to file name. For directories this appends a single slash '/'.
-1 means print one file per line.

With the trailing slash now appended to directories, grep -v '/$' prints everything but those file names.

tail -n+3 is necessary to remove the initial directory and the blank line left over.
Without tail -n+3:

Code:

Music:

Dir/:
Files

With:

Code:

Dir/:
Files

sed 's!Music/!!' removes 'Music/' from the line.
Type man ls in your terminal to read more options available.
