6 Manual use of Man

The Man handbook will give you an outline of the commands and parameters used to teach you how to use them. The man handbook looks dull and stiff. (I thought they were not designed to entertain us.)

But that doesn't mean you can't do anything to make them look beautiful.

Export Pager=most

You need to install ' most '; she will make Your Man handbook more colorful.

You can use the following command to set the specified president for the man Manual:

Export manwidth=80

Finally, if you have a browser available, you can use-H to open any of the man pages in the default browser.

Man-h <command>

Note that the above command only works if you set the default browser to the environment variable $browser.
