Without knowing details, here's a quick & dirty method:
ls | cut -d '_' -f 1 | sort | uniq | xargs -i sox [args here] {}_ru {}_af
{}_output
This makes a few assumptions:
- None of the files have an underscore besides the delimiter before the
suffix.
- All of the files in your directory are *_{ru|af}.
- All *_ru files have a complementary *_af file
- You know what args to pass to sox (because I don't).
