You can set display preferences for a CLI session by using the set command and rows command. The preferences you set apply only to the session you are in. They are not persistent across sessions.
If the preferred number of rows is not specified, it is automatically adjusted based on the actual height of the terminal. If the actual height is undefined, the default number of rows is 24.
For more information, see the man pages for the set command and rows command.
The following example sets a comma to be the field separator, sets GB as the default data-size unit, and sets the number of rows to 50:
cluster1::> set -showseparator "," -units GB cluster1::> rows 50
