I have a directory with subdirectories and files structured like this:
01/fileA 01/fileB 01/fileC 02/fileD 02/fileE 03/fileF 03/fileG 03/fileH 04/fileI
I'd like to get a CSV that looks like this:
01, fileA, fileB, fileC 02, fileD, fileE 03, fileF, fileG, fileH 04, fileI
In other words, I want to generate a CSV with one row per subdirectory, with files listed as columns.
Is it possible to do this from the Linux command line?
