37 This section documents the command-line options to XBoard. You can
38 set these options in two ways: by typing them on the shell command
39 line you use to start XBoard, or by setting them as X resources
40 (typically in your <samp><span class="file">.Xresources</span></samp> file). Many of the options
41 cannot be changed while XBoard is running; others set the initial
42 state of items that can be changed with the <a href="Options.html#Options">Options</a> menu.
44 <p>Most of the options have both a long name and a short name. To turn a
45 boolean option on or off from the command line, either give its long
46 name followed by the value true or false
47 (‘<samp><span class="samp">-longOptionName true</span></samp>’), or give just the short name to turn the
48 option on (‘<samp><span class="samp">-opt</span></samp>’), or the short name preceded by ‘<samp><span class="samp">x</span></samp>’ to
49 turn the option off (‘<samp><span class="samp">-xopt</span></samp>’). For options that take strings or
50 numbers as values, you can use the long or short option names
53 <p>Each option corresponds to an X resource with the same name, so
54 if you like, you can set options in your <samp><span class="file">.Xresources</span></samp> file
55 or in a file named <samp><span class="file">XBoard</span></samp> in your home directory.
56 For options that have two names, the longer one is the name of
57 the corresponding X resource; the short name is not recognized.
58 To turn a boolean option on or off as an
59 X resource, give its long name followed by the value
60 true or false (‘<samp><span class="samp">XBoard*longOptionName: true</span></samp>’).
