There was a problem hiding this comment.
If you export the CID not CID+path you'll have to traverse through the entire graph until you get to the path you were looking for. This could make cat VERY slow for big directories if the content is not in your repo already (and be slow anyway, even if it is).

+1 that - if you pass the path as well as the CID (e.g. /ipfs/Qmfoo/path/to/file.txt) the the unixfs exporter is smart enough to not load whole DAGs for sharded directories, etc which saves a load of time & bandwidth. Maybe this change is better made there?

The command
ipfs cat <hash>/wrong-dir/wrong-filepreviously returned error message:
No such fileFollowing the suggestions given in this thread, I changed the error message to:
no file named "wrong-dir/wrong-file" under <hash>Also, the CI check will fail because test case for this is in interface-ipfs-core. So we'll need to change the tests in interface-ipfs-core repo.
