What is your question exactly?

If it is:

1) Why can't I access my command history with up arrow - down arrow?

Your answer might be dependant upon your shell. Try `echo $SHELL`

Some shells do not have history accessible by default. Bash does for sure. C Shell does not by default but I believe there is a way to enable it.

or

2) How come when I push the up arrow do I see the last bunch of commands I typed?

Your answer is: It makes life simple!


Thanks!

if your command line history doesnt work, make sure you have a file called .bash_history in you home directory, and make sure the permissions are set correctly.
