Most X users can store command-line options in an X startup file like .xsession or .xinitrc. For example, here is the section of my .xsession file used for this book:
xmh -display :0.1 -geometry 660x460+200+5 &
The -display and -geometry options are standard
X Toolkit options; see the
X(1) manual page. Command-line options might be most useful
when you start xmh from an xterm window or a shell
script, or when you want to override resource settings. See the
Section Changing How Commands Work.
You can customize xmh with entries in a resource file like .Xdefaults, instead of, or in addition to, setting command-line options. These override any existing defaults -- though you'll first have to restart xmh, restart X, or give a command such as the following:
% xrdb $HOME/.Xdefaults
