I believe that we will meet the code, each need in the header files, library files and source code files, always need to switch in a few files to switch to, and a file on a terminal window, each time with the mouse point to point, very troublesome, So if you can put these files in the same window and the shortcut keys to switch, then the code is very convenient to compile!The method is simple:1. Open a terminal in the normal way2. Use the combination key ctrl+shift+t, then in the same window ope

Open a terminal in the normal way. 2. Use the combination key ctrl+shift+t, then in the same window opened another terminal, of course, press once again ctrl+shift+t, will generate another, how much you can decide. The effect is as follows:3. Press the combination key alt+1, will switch to the first terminal, press ALT+2, will switch to the 2nd terminal, alt+n, corresponding will switch to the nth terminal.Merging multiple terminals into a single wi

1. Some concepts about terminals: terminals, consoles, virtual terminals, pseudo terminals, control terminals Here first recommend a blog: Linux under the TTY, console, virtual terminals, serial, console (console terminal) detaile

I saw a good article about the pseudo-terminal. I posted it and studied it in another day. Many network service applications such as L2TP, PPTP, and Telnet on Linux use pseudo terminals. Some may ask about this concept and write down what I know for discussion. I. TerminalTo understand the Pseudo Terminal, let's take a look at what is the terminal ). A terminal is a type of terminal device. It has multiple types and generally uses tty for short. 1. Se

We have made a lot of introductions and explanations on the Unified Communication System, and you must have some knowledge about it. Now, let's give a detailed description of the Terminal Services and system construction of the Unified Communication System. Let's start with the terminal type. Terminal Terminal: divided into fixed terminal and mobile terminal. Fixed terminals include IP phones, videophone phones, conference phones, HD desktop video

Solutions for overlapping various terminal letters in ubuntukylin, and ubuntukylin Terminals Ubuntukylin14.04 everything is quite consistent with Chinese usage habits, but the problem of overlapping terminal letters is especially serious. (In fact, ubuntu14.04 also has this problem) As a result, many useful terminals cannot be used, such as guake and tilda. although the built-in terminal can be used, it i

I mean there is something speechless, and we will do what you teach! Or what you force! (Sorry, I am a philosopher) Classification of 0x003 Terminals My classification is relatively simple, and simple classification is helpful for the bypass methods described below Mouse and mouse operat
