![]() The nice thing is that while it resets the output, it does not reset the history of the current session, so you can still use CTRL R or the Up Arrow key. ![]() It works because "\e" is the ESCape code, and the "ESC c" sequence sends the RIS (Reset to Initial State) command to ANSI Terminals. It clears the terminal and the scroll buffer. ![]() Today I decided that enough is enough! I have to find a better way of clearing the screen. and I did! Apparently running the following command does exactly that: to test the most recent changes.Ī common way to do that is to use the `clear` command, or its keyboard shortcut CTRL L. The problem is that while it clears the current screen, it does not clear the scroll buffer, so on programs that generate lots of output, and clearing is most helpful, this is not very effective because scrolling up shows all of the old output again, making it difficult to find where the old output ended and the new one began (sure, I add blank lines like everyone else but good luck finding them with touchpad edge scrolling on a laptop). Screen|VT 100/ANSI X3.64 virtual terminal,Ĭolors#8, cols#80, it#8, lines#24, pairs#64,Īcsc= \,\,-.When working in a Terminal window, I many times need to clear the previous output, especially if the program writes a lot of output and I need to easily tell the difference between executions, e.g. # Reconstructed via infocmp from file: /lib/terminfo/s/screen We can examine a typical terminfo entry using the infocmp command followed by a terminal type name: ~]$ infocmp screen Our Linux system contains a database called terminfo that describes them. While we will encounter these 3 types most often, there are, in fact, thousands of different terminal types. Other common terminal types are “linux” for the Linux console, and “screen” used by terminal multiplexers such as screen and tmux. In this example, we see that our terminal type is named “xterm” suggesting that our terminal behaves like the classic X terminal emulator program xterm. If we examine TERM, we can see this: ~]$ echo $TERM When we start a terminal session on our Linux system, the terminal emulator sets the TERM environment variable with the name of a terminal type. In their heyday, there were many kinds of terminals and they all used different sequences of control characters to manage their screens and keyboards. Long ago, when computers were centralized, interactive computer users communicated with remote systems by using a physical terminal or a terminal emulator program running on some other system. Tput is part of the ncurses package and is supplied with most Linux distributions. Tap and drag an app from the Dock to the far left or. Click sign at the bottom left and choose your keyboard shortcut, like Shift CMD T. It comes bundled with a ton of helpful functions, helpers, plugins, themes and a few things that make. On your iTerm, press CMD , to open settings. Oh-My-Zsh is an open source, community-driven framework for managing your ZSH configuration. I’d like to duplicate a tab with the same directory. Terminal
