command linexterm
I can issue the clear command or press Ctrl + L to clear the current Ubuntu terminal, but this just shifts previous output upwards and if you use mouse scroll or PgUP and PgDown keys it's hard to distinguish where the output of previous command ends and output of current command begins.
Is there a way to really clear the terminal so I won't see previous command results?
According to https://help.gnome.org/users/gnome-terminal/3.8/adv-keyboard-shortcuts.html.en, there are some shortcuts that cannot be edited in gnome-terminal. These are exactly: Ctrl+Shift+↑ and Ctrl+Shift+↓:
In Xubuntu you can use Ctrl+↑ and Ctrl+↓ because Xubuntu uses xfce4-terminal which is different by gnome-terminal. The same happens with other distros.
# in some configuration files and programming languages marks comments and is excluded from execution.
Run a command and then create a hashtag using # of the command so that we can find it later.
some-command #mycommand
for example:
sudo dmidecode | grep -A 9 "System Information" #sysInfo
Now I create a hash tag #sysInfo for the command sudo dmidecode | grep -A 9 "System Information" which is used to show system information.
Now search for the hash tag in reverse-i-search (press ctrl+r), in the terminal and type #sysInfo.
You may create as many hash tags for every command and find it later using reverse-i-search.
Note: hashtag used here is not really the same concept as we know in social media. This word is just used to clarify and make it easy for newbies to understand the answer.

Yes, the command you're looking for is
In contrast to
clear, or Ctrl+L,resetwill actually completely re-initialise the terminal, instead of just clearing the screen. However, it won't re-instantiate the shell (bash). That means that bash's state is the same as before, just as if you were merely clearing the screen.As @Ponkadoodle mentions in the comments, this command should do the same thing more quickly:
From the other answers:
You can set a Keyboard Shortcut to
resetthe terminal, as explained by towolf.If you're running Kubuntu, and your terminal is Konsole, you need to go to Edit → Clear history, since
resetdoesn't work the same way there, as UncleZeiv notes.
