That's my mistake, I should have read the document of Nautilus. It's OK for the failed commands. 'mkdir' is enough for me at present. Thanks Rishabh, I will try it on Octopus cluster. Rishabh Dave <ridave@redhat.com> 于2020年7月14日周二 下午11:15写道：

When I use cephfs-shell, I find that some commands are useless.
That's odd, either the command should be absent or should run successfully. On inspecting the source code, listxattr command is actually absent in Nautilus; it's available Octopus onwards.
And I am forced to use the interactive mode.
Yes, that is one issue with cephfs-shell that got fixed recently. The fix is clearly not backported to Nautilus (that is Ceph version 14) from the output you attached in your email.
I'm not sure if I use it in the correct way or not. Is there a more clear document?
AFAIK no. But I would like to point out that the doc you are referring (https://docs.ceph.com/docs/master/cephfs/cephfs-shell/) is for latest version of cephfs-shell, Nautilus has lesser features (for example, listxattr command is present in master but absent in Nautilus)
