So, as I have used the three files first_file, second_file, and third_file to view the content.

So, to see the content of the next file you have to use SPACE key.
How to view move between File using more command?
So, now we will look how we can use SPACE, b, -c, and p option.
First we will use a SPACE key option to display the new lines.
So, with the SPACE you can also use z key to scroll down by one page.
If we have to move in the backwards direction by one page then will use b key.
So, -c option instead of scrolling the next content, it will clear the screen and then display the new content.
Command: #more -c more_example
Now, let’s have a look on -p option so instead of scrolling the next content it will shift on the upper side.
Command: #more -p more_example

To set the size of the screen we will use -(minus) sign with the screen size set as a number of lines.
Command: #more -12 more_example
In the above example, we have used -12 means it will make one page of 12 lines and display the output.
So, after hitting SPACE key, you can see the next page of 12 lines only and when you will use b key it displays the previous 12 lines.

Suppose we have to search the word “Hostname”, then we will +(plus) sign and then use the word, means it will be like +/Hostname.
