Tilix, A Good Terminal You Need
This terminal offers all the morden things that you need:

- Drop-down terminal split screen
- All the terminal and tab initial positions are configurable.
Official Tilix packages are available for Ubuntu artful and bionic. sudo apt-get install tilix ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For older versions: sudo add-apt-repository ppa:webupd8team/terminix sudo apt-get update sudo apt-get install tilix
Tilix provides a drop-down termianl option but there is not shortcut keybound inside the Tilix for this feature.
Inorder to do so, we simply add a custom shortcut in the Ubuntu keyboard.
shortcut in the application launch and create a new shortcut for
It is tricky that you need to click the F12 position (as shown in the picture) to assign the key to enable this shortcut.
Fixing the issue
Fortunately fixing this issue is quite easy, you can do either of the two options below.
Source vte.sh in bashrc
Update ~.bashrc (or ~.zshrc if you are using zsh) to execute vte.sh directly, this involves adding the following line at the end of the file.
if [[ $TILIX_ID ]]; then source /etc/profile.d/vte.sh fi
On Ubuntu (16.04), a symlink is probably missing. You can create it with:
ln -s /etc/profile.d/vte-2.91.sh /etc/profile.d/vte.sh
Install Deb. Pkg from Command Line
You can install it using
sudo dpkg -i /path/to/deb/file followed by sudo apt-get install -f .
How to fix "because the public key is not available" issue
There are times when running apt-get update in Ubuntu will result in error messages such as the following:
sudo apt-get update XXX: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32
Easy fix, copy the key and run this:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5
Echo & Touch
echo 'something' >> file_name
>> will append your ‘something’ into the end of the file
The ‘>’ will replace the file with a new file that has the ‘something’
touch file_name will create a new file.

Static IP Configuration
I try to use CLI modify the files under
/etc/network/interfaces but failed.
The easiest thing to do it is put in a monitor and open the network configs. in the tab IPv4 Settings, switch the method to Manual and Add the static IP address that you want.
