Elementary OS shows a warning message when you copy and paste the command lines from the internet browser to the Terminal, like you do it all the time when following our tutorials. Although the warning may be OK for beginners, it can become a frustrating experience and the additional click on ‘Paste Anyway’ may become a unwanted extra step. Thankfully, it is very easy to turn it off using the ‘dconf-tools’.
STEP 1: INSTALL DCONF EDITOR
Go to ‘Applications’, and launch the ‘Terminal’. Copy and paste the following command in the terminal to install ‘dconf-editor’.
sudo apt-get install dconf-tools
You will have to type ‘Y’ to confirm installation.
STEP 2: CONFIGURE DCONF TO TURN OFF TERMINAL WARNING MESSAGE
Go to ‘Applications’ and type ‘dconf editor’ and launch it.
Navigate to the following path in the dconf editor dialog box: org > pantheon > terminal > settings > unsafe paste alert.
Uncheck the ‘unsafe-paste-alert’ option in the right pane. That’s it. You will no longer see that alert message in terminal. Anytime if you want it back, you can come to same option in dconf editor and check the box.
