"reset" or "clear" will both clear your terminal. "reset" does a bit
more, such as set it back the way it was when you started, in case
some control characters have changed something. For example if you
run 'cat somefile.jpg", somefile.jpg is not plain text so will probably
mess up your terminal in some way.
If you are using "bash", "history -c" will clear the your command history,
and "history -r" will read it again from the history file. So if you do
"history -c; history -r;" your history will be back to what it was when
you started your terminal session.
Combining all three will pretty much put your teminal back to the way it
was when you opened it. This will not clear any variables you may have
set.
"history -c; history -r; reset;"
If this is something you do frequently, you may want to append a line to
your .bashrc file,
alias histscreenclear="history -c; history -r; reset;"
to condense them into one command.
=======================================================
history -c will clear the entire bash history.
To only clear the current session history use:
history -r.

even after running clear or history -c, which I find is the best
option to add to ./bash_logout, I can still scroll my putty screen and
see what all I have done. Is there any way to completely erase this
information.

Kumar asked about clearing the information from his putty window.
To do so -
1. Right click on the top bar of the putty window
2. A Context menu will appear
3. Select “Clear Scrollback”
This will erase all details of your session from putty’s scrollback buffer.
