A simple script for serving one store with all rclone remotes as directories. I use this as a daemon which can be accessed with dolphin :)

rclone-serve-combined

#!/bin/bash

# `rclone serve -h` for other remotes / arguments
PROTOCOL="webdav"
ARGS="--vfs-cache-mode writes"

# we construct an inline combined upstream with all remotes using the remote name as the directory
rclone listremotes \
  | awk -F':' -v ARGS="${ARGS}" -v PROTOCOL="${PROTOCOL}" "
BEGIN {
  printf \"rclone serve \"ARGS\" \"PROTOCOL\" ':combine,upstreams=\\\"\"
} {
  printf \" \"\$1\"=\"\$0
}
END {
  printf \"\\\":'\"
}" \
  | sh -
