Appendix C Using the Command-Line Interface Command Output Paging Table C-2 Using Special Characters in Regular Expressions Character Type Character Special Meaning period . Matches any single character, including white space. asterisk * Matches 0 or more sequences of the pattern. plus sign + question mark ?1 Matches 1 or more sequences of the pattern. Matches 0 or 1 occurrences of the pattern. caret ^ Matches the beginning of the input string. dollar sign $ Matches the end of the input string. underscore _ Matches a comma (,), left brace ({), right brace (}), left parenthesis, right parenthesis, the beginning of the input string, the end of the input string, or a space. brackets [] Designates a range of single-character patterns. hyphen - Separates the end points of a range. 1. Precede the question mark with Ctrl-V to prevent the question mark from being interpreted as a help command. To use these special characters as single-character patterns, remove the special meaning by preceding each character with a backslash (\). Command Output Paging On commands such as help or?, show, show xlate, or other commands that provide long listings, you can determine whether the information displays a screen and pauses, or lets the command run to completion. The pager command lets you choose the number of lines to display before the More prompt appears. When paging is enabled, the following prompt appears: The More prompt uses syntax similar to the UNIX more command: • To view another screen, press the Space bar. • To view the next line, press the Enter key. • To return to the command line, press the q key. Adding Comments You can precede a line with a colon ( : ) to create a comment. However, the comment only appears in the command history buffer and not in the configuration. Therefore, you can view the comment with the show history command or by pressing an arrow key to retrieve a previous command, but because the comment is not in the configuration, the write terminal command does not display it.
