42Basic Command-Line Interface Commands
show begin
Once you specify a filter for a show command, you cannot specify another filter at the next --More--
Note
prompt. The first specified filter remains until the more command output finishes or until you
interrupt the output. The use of the keyword begin does not constitute a filter.
Because prior output is not saved, you cannot search or filter backward through prior output.
Note
A few show commands that have long output requirements do not require user input at the --More--
prompt to jump to the next table of output; these types of output require you to enter the same number
of Ctrl-^ or Ctrl-Z combinations as there are --More-- prompts to completely abort output.
Examples
The following is partial sample output of the show interface | begin command that begins unfiltered
output with the first line that contains the regular expression “Ethernet.” At the --More-- prompt, the user
specifies a filter to show only the lines in the remaining output that contain the regular expression
“Serial.”
