linux Oracle VM can't see full output from commands such as ls

Hello,

I'm using I believe the JetOS version of linux. It's Oracle VM.

It's all command line.

When I do for example any command that lists results:

ls
ls -ltr
cat

I can only see the end of the results on the screen.

In other words, I can't scroll up to see all the results.

Is there some kind of paging parameter I can use to see just a section of the results at a time and hit enter
and then go down a few lines see the next results etc?

You can pipe the output through a pager such as "less". When using ls (i.e. without -l) you want to format by rows instead of columns using "ls -x". Personally I like to also use the -F option of ls, to show which entries are directories, executables and so on.
Instead of using "cat", use "less" directly.

Have you tried Shift-Page_up and Shift-Page_down? These normally give a degree of scrolling on text-only systems if you are actually at the console, may not necessarily work in a VM
ls -Fx | less
less afile
ls -Fltr | less
ls -Flt | less

Actually "ls" is a bit more awkward to paginate than most commands because it behaves differently when stdout is a pipe. See below (lines starting # are comments)
# First determine the width of your screen
07:35:12$ stty size
25 80
 
# The second number is the width. Give this to ls (only seems to work if you also give -x)
09:06:58$ ls -xw80|less
Account.cpp               Account.cpp.bu    Account.h
Account.h.bu              Bordered$1.class  Bordered.class
Bordered.java             Bounds$1.class    Bounds$BoxedLabel.class
Bounds.class              Bounds.java       EtherLinkXL.c
 
# (further output suppressed)
# ls -Fxw80|less also works
