is actually no tutorial in a real sense. It is a simple tip which
many newcomers would appreciate. Most of the Linux commands that
you type create a lot of text at the output, and generally this
text scrolls off the screen. Pressing the <Up Arrow> key
simply gets the last command executed and doesn't let you see
the text that scrolled up the screen. So how do you do it??
You have to press <Shift> + <Up Arrow> keys
to scroll the screen in the upward direction. Similarly once you
have scrolled up you can use the <Shift> + <Down Arrow>
key to scroll downwards. Alternatively you can press <Shift>
+ <Page Up> to scroll one page at a time and <Shift>
+ <Page Down> would scroll down a page at a time.
Once you have scrolled many pages upwards if you want to come
back to the prompt you can simply leave the <Shift> button
and press any other key such as <Page Down> or <Page
Up> or the <Right Arrow> or <Left Arrow> key.
That's it for this .. I though this tip would be worth adding
to this website. Once you know this trick you would be using this
almost every time you do some serious stuff in the shell.
