Many commands have a singular version (for example, workspace) that provides for create, modify, and delete of an individual element. The plural version of that same command (for example, workspaces) lists all those elements. This makes descriptions of what you're trying to achieve using a command grammatically correct, except of course for the few commands such as
filelog which aren't actual English words.
Many commands provide a preview capability. Unlike most systems, Perforce preview output is the same as the output generated for full functionality. This can be very useful for development and debugging. The
–n option provides preview for the commands that support it.
