Appendix C Using the Command-Line Interface

Command Output Paging

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 if 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:

<--- More --->

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.
