Error message
trailing args detected: %s
What it means
The joinbysnapshotstatus command takes no positional arguments; its RunE rejects any invocation with extra args using this fmt.Errorf message that includes the offending args. It is a cobra CLI arity guard ensuring the status query runs only with flags and no trailing tokens.

Solutions
- Rerun without positional args: `peer channel joinbysnapshotstatus`.
- Quote glob patterns or variables so the shell does not expand extra tokens into args.
- Remove stray arguments; the command reports status across channels via flags only.
Example fix
// before peer channel joinbysnapshotstatus mychannel // after peer channel joinbysnapshotstatus
Defensive patterns
Strategy: validation
Validate before calling
// bash if [ "$#" -ne 0 ]; then echo "joinbysnapshotstatus takes no positional arguments"; exit 2 fi peer channel joinbysnapshotstatus
Prevention
- Never pass positional args to joinbysnapshotstatus — use flags only.
- Quote variables/globs in shell to prevent accidental argument expansion.
- Check `--help` for the exact usage before scripting a subcommand.
When it happens
Trigger: Running `peer channel joinbysnapshotstatus <anything>` where <anything> is one or more trailing positional arguments (e.g. a channel name or snapshot path passed by mistake).
Common situations: Assuming the status command takes a channel ID argument; shell glob expansion accidentally appending filenames; copy-paste from the joinbysnapshot command which does take flags/paths.
