not enough arguments for 'target'

Error message

not enough arguments for 'target'

What it means

The 'target' terminal command dispatches on its first argument (subcommand). With no subcommand at all (bare 'target'), it returns this error. Valid subcommands include e.g. listing targets and 'follow-exec'.

Solutions

1. Provide a subcommand, e.g. 'target list' to show all targets, or 'target follow-exec ...'.
2. Run 'help target' to see the available subcommands.
3. If you wanted the current target information, use the appropriate subcommand rather than bare 'target'.

Example fix

// before
target
// after
target list

if strings.TrimSpace(cmdline) == "target" { return errors.New("target requires a subcommand, e.g. 'target list'") }

When it happens

Trigger: Running 'target' with no arguments, so the switch matches the empty-string case.

Common situations: Users expecting a bare 'target' to list all debugged processes, or pressing the command before completing it.
