研究方向
The issue asks to implement a command that blocks until a selected command finishes. Start by examining existing diagnostic commands in the repository, particularly the `ipfs diag cmds` command (source likely in `commands/diag.go` or similar). Review the referenced issue #3114 for context on why this is needed. Check if there are any existing implementations or discussions in the comments. The implementation should follow the pattern of other IPFS commands, using the command framework provided by go ipfs. Pay attention to how commands are registered and how to wait for command completion.
