How to obtain same effect as 'less' in Linux in mysql?

 How to obtain same effect as 'less' in Linux in mysql?


i.e. the output display stops at the first screen, before you can move the output in vi way.

$pager less

$select * from table;

Furthermore, use -

$pager less

$select * from table\G

so that fields are displayed from up to down, instead of from left to right.
