Discussion

Each listed completion is the configuration statement at the top of a particular configuration
hierarchy. For example, the statement protocols is at the top of the hierarchy
in which you configure all JUNOS routing protocols:
[edit]
aviva@router1# edit protocols ?
Possible completions:

> connections Circuit cross-connect configuration
> dvmrp DVMRP options

| Pipe through a command
If you move down through the hierarchy—for example, into the protocols portion—
the prompt changes to [edit protocols] to show you where you are:
[edit]
aviva@router1# edit protocols
[edit protocols]
aviva@router1#
Learning About the CLI While on the Router
In some of the command lines in the previous section, we showed how to use the ?
to get context-sensitive help about the CLI and the software. This feature is part of
the CLI’s built-in help, and you will find yourself using it regularly. When you type a
? at a prompt, the CLI shows a list of commands or statements you can use, along
with a short description of the command or statement. If you partially type a command
or configuration statement name and then type a ?, you see a subset of the
available commands or statements.
