checking the sources for a while... the prefix before / shouldn't be there...

roboflow upload -p horserider10k-aubbj val_000001.jpg

loading Roboflow workspace...
loading Roboflow project...

nice this works, according to docs I should be able to do

roboflow upload *.jpg

not really

roboflow upload -p horserider10k-aubbj *.jpg

usage: roboflow [-h] [-v] {login,download,train,upload,import,infer,project,workspace,upload_model,get_workspace_info,run_video_inference_api,deployment,whoami} ...
roboflow: error: unrecognized arguments: val_000001.jpg val_000002.jpg val_000003.jpg val_000004.jpg ...

passing the wildcard to the cli directly doesn't work either:

roboflow upload -p horserider10k-aubbj '*.jpg' 

loading Roboflow workspace...
loading Roboflow project...

FileNotFoundError: [Errno 2] No such file or directory: '*.jpg'

after some more tinkering...

roboflow import -p horserider10k-aubbj -r 5 .

did the job.

Start with the upload and import command handling in roboflowpy.py, especially upload_image, and inspect workspace.py where project IDs are resolved. Reproduce the documented commands with a single image, a wildcard, and the import fallback. Done means the CLI behavior and documentation agree, including project selection and multi-image uploads.
