In
computing, xterm is the standard
terminal emulator for the
X Window System. A user can have many different invocations of xterm running at once on the same
display, each of which provides independent
input/output for the
process running in it (normally the process is a
Unix shell).xterm originated prior to the X Window System. 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. 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
[1], "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."
