Just an FYI; that worked perfectly. A super simple arj command, whether on DOS, *nix, Windows or MacOS;

arj a -r -v1440 filename.arj subdir/

Cuts whatever yer compressing into filename.arj, a01, a02, etc.

Then, you can create .img files if needed, for say a Gotek device, with;

dd if=/dev/zero of=filename_arj.img bs=1440k count=1
dd if=/dev/zero of=filename_a01.img bs=1440k count=1
....
mkfs.msdos -F 12 filename_arj.img
mkfs.msdos -F 12 filename_a01.img
....
mkdir disk
sudo mount -o loop filename_arj.img disk
....
cp filename.arj disk
....
sudo umount disk/

And then you have .img files of the different .arj, .a01, etc to copy over to the DOS machine via floppy, OR Gotek .img.

Meh...
