When you use Ubuntu, basically, the following basic terminal program is included.
As it is a basic terminal, it is faithful to basic, but there is one inconvenience. When you open multiple terminals, the previously opened terminals are hidden from the back.
So what I found is a program called a terminator.
If you use a terminator, you can use the following without hiding the previous window.
Vertical / horizontal user can freely divide.
Installation is as follows. (Root privilege required)
# apt-get install terminator
Fedora / RHEL
# yum install terminator
# conary update terminator
# zypper install terminator
# urpmi terminator
Shortcuts are also possible, but there are many kinds, so I tried to list only those that I use often.
Ctrl + Shift + O
Horizontal split based on current Focus
Ctrl + Shift + E
Vertical split based on current Focus
Alt + Up
Move focus to upper window with current focus
Alt + Down
Move focus to bottom window based on current focus
Alt + Left
Move focus to left window based on current focus
Alt + Right
Move focus to right window based on current focus
Unless you connect linux via ssh or telnet, you should install and start the terminator unconditionally. It is a useful program than I thought.
