It was originally written as a stand-alone terminal emulator for the VAXStation 100 (VS100) by Mark Vandevoorde, a student of Jim Gettys, in the summer of 1984, when work on X started. They are just programs offering you a frontend (Graphical user interface) for your used shell programs like Bash or zhs (or original sh) what are responsible to present your textual input, parse it and then send it to. It rapidly became clear that it would be more useful as part of X than as a standalone program, so it was retargeted to X. As Gettys tells the story, "part of why xterm's internals are so horrifying is that it was originally intended that a single process be able to drive multiple VS100 displays." Īfter many years as part of the X reference implementation, around 1996 the main line of development then shifted to XFree86 (which itself forked from X11R6.3), and it is now maintained by Thomas Dickey. Theres a terminfo entry for putty-256color shipped with ncurses like the rest of the terminfo entries. Most terminal emulators for X started as variations on xterm.In linux they can all look the same from the point of view of the user at the keyboard. The differences are in how they interact with each other. The shell is the program which actually processes commands and returns output. Most shells also manage foreground and background processes, command history and command line editing. Anything you cut (-X) and copy (-C) is stored in the clipboard and the system further reads it from the clipboard when you use paste (-V). These features (and many more) are standard in bash, the most common shell in modern linux systems.Ī terminal refers to a wrapper program which runs a shell. A selection is not put into the Terminal automatically. The selected text you copied is initially stored in a place called the ‘pasteboard’. XTerm, on the other hand, only uses the clipboard. Decades ago, this was a physical device consisting of little more than a monitor and keyboard. As unix/linux systems added better multiprocessing and windowing systems, this terminal concept was abstracted into software. Now you have programs such as Gnome Terminal which launches a window in a Gnome windowing environment which will run a shell into which you can enter commands. UXTerm is XTerm with support to Unicode characters. #DIFFERENCE BETWEEN UXTERM AND XTERM WINDOWS#.
