Whenever you’re using the terminal extensively you may find your terminal cluttered with commands and output. This can be rather annoying and even confusing at times with the bash prompt at the bottom of your terminal screen. The solution to this is to clear or reset terminal.
To clear or reset the terminal in linux is a simple task. We will go over a few commands to do this. Each command will have a notable difference and will be up to you which serves your needs best.
Assuming your terminal is cluttered with commands and output, and your bash prompt is now at the bottom as follows:
DISTRIB_ID=Ubuntu DISTRIB_RELEASE=18.04 DISTRIB_CODENAME=bionic DISTRIB_DESCRIPTION="Ubuntu 18.04.3 LTS" NAME="Ubuntu" VERSION="18.04.3 LTS (Bionic Beaver)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 18.04.3 LTS" VERSION_ID="18.04" HOME_URL="https://www.ubuntu.com/" SUPPORT_URL="https://help.ubuntu.com/" BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/" PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy" VERSION_CODENAME=bionic UBUNTU_CODENAME=bionic gametheory@ubuntu:~$
You can run the clear command to clean the terminal and have your bash prompt back at the top.
Now notice that after running the clear command you can scroll up with your mouse wheel to see previous output. Essentially the clear command just pushes the clutter up and out of view.
You can also use the keyboard shortcut “Ctrl + L” to achieve the same as the clear command.
The reset command also cleans up the clutter by re-initializing your terminal. However, the difference is that you cannot scroll up to view previous output. This resets the terminal like if you were opening it for the first time.
Notice that when you run the reset command the terminal takes 1-2 seconds to re-initialize.
tput reset command:
The tput reset command does the same as the reset command. The difference here is that it resets the terminal instantly.
I mostly use the clear command, but occasionally when I don’t want my terminal scrollable, I use the reset command instead. That is all for this quick look at how to clear or reset terminal in linux.Tags: tutorials, linux
