25-36Resources & Command Line OptionsThe following sections describe the most common sources of resource entries; thesections are ordered according to priority - e.g. command line options overrideduplicate entries in the .Xdefaults file.Command LineEntries on the command line override any other settings specified in other resourcefiles. Whilst most general attributes have equivalent command line arguments,heirarichal ones seldom do have direct equivalents. For example:*foreground: red has the command line equivalent: -fg red*Settings: red does not have a direct equivalent.Although the latter does not have a direct command line option equivalent, it can stillbe specified on the command line by using its resource string directly. For example:-xrm “*Settings: red”Application DefaultsThe application defaults file usually exists in /usr/lib/X11/app-defaults. The file inwhich the resource entries are put is the name of the application with the first twoletters capitalised; the application name is hard coded by the X client vendor and isunchangeable.The application defaults file name for TeemTalk with graphics emulation support isxteemx340, and for TeemTalk with no graphics support it is xteemx320. TheApplication defaults file sets resources globally for applications and therefore setspreferences for all users of the application..XDefaultsThe .Xdefaults file is located in a specific user's ‘home’ directory and is processed forall applications and is not therefore specific to a particular application. Since it islocated in the user's ‘home’ directory it only affects instances of the applicationsstarted by users whose home directory it is.Unlike the Application Defaults and Command Line options which are merged intothe resource database when an application is started, the entries in the .Xdefaults fileare only read once when the X server is started. Therefore changes made to the.Xdefaults file will not affect applications until the next time the X Server is startedand the .Xdefaults file re-read.
