¡spec (1) (CSS Utilities) spec (1)NAMEspec-ray diffractometer control and general data acquisition packageSYNOPSISspec ¢¤£¦¥¨§© ][¢¤ [ ][¢ geometry ][¢ my_name ][¢ user ][¢ tty ][¢¤fake_tty][¢¤ debug ][¢¤ option=value fd ][¢ pid directory ]DESCRIPTIONspec provides a software environment for the operation of an X-ray diffractometer and otherdata-acquisition instruments. spec contains a sophisticated command interpreter that uses aC-like grammar and is partially modeled on the standard UNIX utility awk. spec supports avariety of X-ray diffractometer configurations. The diffractometer geometry is chosen by theprogram name. Those currently supported include:spec eneric instrument controlfourc tandard four-circle diffractometertwoc tandard two-circle diffractometersixc ix-circle diffractometer (δ, θ, χ, φ, µ, γ)psic nS4-D2 six-circle diffractometerkappa appa diffractometersurf arious liquid surface diffractometerszaxis tandard z-axis diffractometerThe following options are recognized:¢£¢¥¢§¢©¢¢¢Fresh start. All symbols are set to their default values and the standard macrosare read to establish the default state.Clean and fresh start. All symbols are set to their default values but no commandfiles are read and no macros are defined. Only the built-in commands are available.Simulation mode. No hardware commands are issued. If started in simulationmode, simulation mode cannot be turned off without restarting the program.Yes, change motor controller registers initially if they disagree with the settingsfile. Normally, spec requires you to confirm such a change. This flag would beuseful if you know controller power had been turned off.Indicates that spec should operate in quiet mode and allow output to all devices tobe turned off. This option is only valid when used with ¢¤ the option.geometryForce loading of macro files and activation of geometry calculations for the specifiedgeometry, while using the configuration files taken from the name by whichspec is invoked.my_nameUse my_name for setting the interactive prompt and the name of the directory containingthe config, settings and state files. Normally the name by which spec isinvoked is used.¢ user Use user’s last saved state as the current user’s initial state.tty Use the current user (or user’s) last saved state from the terminal specified by tty.¢The terminal can be specified ¢¤ as /dev/tty01 ¢¤ or tty01.MANUAL PAGE 279
