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:
<--- More --->
The More prompt uses syntax similar to the UNIX more command:
•

•

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.
