FILES¢¢fake_ttyThis option creates a user state associated with fake_tty, which may be any name.This option allows you to bypass the locking feature that prevents multipleinstances of spec to be started by the same user from the same terminal.debug Sets the initial value of the debugging variable DEBUG to debug. The availabledebugging categories are described on page 57 in the Reference Manual. A value of192 is useful for debugging hardware problems.-o option=valueInitializes the spec_par() option to value. The available spec_par() options aredescribed on page 76 in the Reference Manual.¢fd pid Indicates that spec input is coming from a pipe from another program. The argumentfd is the file descriptor that spec should use for standard input. The argumentpid is the process ID of the spawning process. If fd is zero, spec will not reechoinput from the file descriptor to spec’s standard output.direc Use direc instead of the compiled-in name (usually /usr/local/lib/spec.d) ortheSPECD environment name as the auxiliary file directory.(SPECD is the auxiliary file directory,normally /usr/local/lib/spec.d.)(geom is the first four letters of the name by which spec was invoked.)(spec is the complete name by which spec was invoked, as in fourc, twoc,etc.)./spec.macSPECD/site.macSPECD/site_f.macSPECD/standard.macSPECD/geom.macSPECD/spec/geom.macSPECD/spec/configSPECD/spec/settingsSPECD/spec/conf.macSPECD/spec/userfiles/hdw_lockSPECD/spec/userfiles/user_tty.SSPECD/spec/userfiles/user_tty.PSPECD/spec/userfiles/user_tty.LSPECD/help/∗Optional private command file always read at start-up.Optional site command file always read at start-up.Optional site command file only read when starting fresh.Standard macro definitions.Geometry macros.More geometry macros.Hardware configuration file.Motor settings file.Optional configuration command file always read at start-up.Spectrometer lock file.User ’sstate file.
