'''xterm''' is the standard [[Wikipedia:Terminal emulator|terminal emulator]] for the [[X Window System]]. It is highly configurable and has many useful and some unusual features.
The ultimate authorities for using and customizing xterm are the ''man pages'' for ''xterm, uxterm, koi8rxterm, ''and ''resize; ''the [http://invisible-island.net/xterm/xterm.faq.html XTerm FAQ] and the [http://invisible-island.net/xterm/xterm.log.html XTerm ChangeLog].
Xterm is used with different hardware on a variety of operating systems, not just with a PC keyboard on a GNU/Linux system.  There are several options to set in your X resources files that make this terminal emulator much easier to use with Linux.
*Allow xterm to report the '''TERM '''variable correctly.  '''Do not '''set the TERM variable from your ''~/.bashrc'' or ''~/.bash_profile'' or similar file.  The terminal itself should report the correct TERM to the system so that the proper ''terminfo'' file will be used.  Two usable terminfo files are ''xterm, ''and ''xterm-256color.'' The [http://invisible-island.net/xterm/xterm.faq.html#xterm_term XTerm FAQ] state, "The xterm-color value for $TERM is a bad choice..."
:– Without setting TERM explicitly, xterm should report {{ic|$TERM}} as {{ic|xterm}}.  You can check this with either of these commands:
{{bc|$ echo $TERM
$ tset -q}}
:– When TERM is not set explicitly, color schemes for some programs, such as ''vim, ''may not appear until a key is pressed or some other input occurs.  This can be remedied by setting the resource {{ic|termName}}, either from the command line with {{ic|xterm -tn xterm-256color}}, or by setting the resource value:
xterm*termName: xterm-256color
*Use '''UTF-8. '''First make certain your locale settings are correct for UTF-8, then add this to your resource file so that xterm interprets all incoming data as UTF-8 encoded:
XTerm*locale: true
*Fix the '''Alt '''key. {{Keypress|Alt}} is not the {{Keypress|Meta}} key, yet on PC keyboards {{Keypress|Alt}} is used as the {{Keypress|Meta}} key.  Make xterm aware of this by adding the following to your resource file:
XTerm*vt100.metaSendsEscape: true
As new lines are written to the bottom of the xterm window, older lines disappear from the top.  Xterm saves these lines in a buffer and they can be recalled by scrolling.  The mouse wheel should just work, and the combinations of {{Keypress|Shift+PageUp}} and {{Keypress|Shift+PageDown}} will scroll one-half a page at a time, or one can use the [[#The Scrollbar|scrollbar]].
The number of lines saved for recall is set at 1024 by default in Arch.  You can change this with the {{ic|saveLines}} resource,
Xterm*saveLines: 4096
Normally, text output would be scrolled one line at a time.  This would cause some delay when commands produce a lot of output.  The resource {{ic|jumpScroll}} is set to ''true ''by default so that multiple lines at a time can be printed.  Two other resources that affect scrolling speed are {{ic|multiScroll}}, for asynchronous scrolling, and {{ic|fastScroll}}, which suppresses refreshing the display when there is a large amount of output.  Both of these are set to ''false'' by default.
