Command History	The bridge/router “remembers” the 10 most recent commands you
Substitution	entered. To display a list of these commands, enter:

	history substitution option syntax.
Table 19 History Substitution Option Syntax
Syntax	Description
!!	Repeats the previous command.
!<n>	Repeats the command line numbered n.
! –<n>	Repeats the command whose number is the current command number minus n. The
	current command number is printed on the screen preceding the prompt. For
	example, if the current command is 100 and n is 2, command number 98 is repeated.
!<string>	Repeats the most recent command that starts with string. The SHow History command
	might display the following commands:
	166	setdefault !1 -path control = enabled
	167	show -path configuration
	168	show history
	169	set screenlength = 23
	170	setdefault -bridge control = bridge
	171	show statistics ?
	If you enter !setd at the prompt, the most recent occurrence of the SETDefault
	command (setd -br cont = b, number 170) is executed.
!?<string>	Repeats the most recent command containing string.
^<string1>	Repeats the most recent command that contains string1. If string2 is specified, it
^<string1>^<string2>	substitutes for string1 in that command. For example, if you entered this SETDefault
	command with a typing mistake:

seed welcomestring = “You are talking to the 3Com NETBuilder”

To repeat the command with the correct spelling of SETD, you do not need to reenter the entire command. Enter the following command:

^seed^setd

The following command is displayed and executed:

setd welcomestring = “You are talking to the 3Com NETBuilder”
