linux-less command

The less tool is a tool for paging through files or other output and is a powerful tool for Linux to view the contents of a file. Supports search up and down.

1. Command format

Less and more are similar, with less you can browse files at will, and more can only move forward and not move backwards. And less is not going home before viewing the entire file.

-m shows a percentage similar to the more command

-N Displays the line number of each line

-o < file name > save less output in the development file

-Q does not use warning tones

-S displays a row of continuous empty behavior

-S line over a long time will be over partially discarded

-X < number > Displays the "tab" key as a specified number space
