No error code on non-existent object (?)

[sgofferj]

I'm currently trying to rewrite a bash script which copies files from a camera via curl to a WEBDAV server to upload the files to S3 storage. Part of this is to check if folders for month and day exist and if not, create them.

While testing, I did ${S3CMD} ls s3://bodycam/2024/${MONTH} && echo yes || echo no

I noticed that s3cmd seems to always return 0, no matter if the operation was successful, i.e. if the folder exists or not I always get "yes".
Not sure if that makes sense...
