Question 3

A list of commands that start with com.

Question 4

command parm?

Answer 4

This style of help lists all parameters beginning with the parameter type so far. (notice that there is no space between parm and the ?.)

Question 5

command parm<tab></tab>

Answer 5

If you press the tab key midword, the CLI either spells the rest of this parameter at the command line or does nothing. If the CLI does nothing, it means that this string of characters represents more than one possible next parameter, so the CLI does not know which one to spell out.

Question 6

Command parm1 ?

Answer 6

If a space is inserted before the question mark, the CLI lists all the next parameters and gives a brief explanation of each.
