[SOLVED] how do you scroll up in text mode?

[Mad Professor]

Yeah, Centos 5 running in text mode, no X-window or Desktop environment.

Ran a Commnd

hdparm -I /dev/hdd

then my screen got flooded with text, all I see is the end of the output.

Which doesn't give me the information I need.

How does one read the output after a command?

In case more information is displayed on the system and you find yourself at the bottom use the 'less' command to hold the output. Usage

cmd|less

Then use the normal arrow keys to navigate.

Most of the time I pipe it through less.
i.e.
hdparm -l /dev/hdd | less
Then you can use most of the vi commands to read the text:
j - up
k - down
G - bottom
g - top
C-D - page down
C-U - page up
/ - search
n - next (search term)
N - previous (search term)
q - quit

EDIT: Too slow!

If you find you do need to scroll up in a bash terminal after the fact, you can do so with Shift+PgUp, though I would recommend the use of less or a similar texttrap. You can pipe it to a file for later perusal while letting it still go to your screen if you use tee

hdparm -l /dev/hdd |tee logfile.log

This will let run as normal but also put its contents into logfile.log.

As other have said you can pipe the command through less. However, when the output is scrolling you can use scroll lock (Ctrl+s) to stop the text scrolling and Shift+PgUp to scroll back over what has already been displayed. Use Ctrl+q to unlock scroll lock and resume scrolling. This will work for any screen output such as kernel boot messages and compiler output.
