. Unix considers any device attached to the system to be a file. And that includes your terminal! . By default, a command treats your terminal as the standard input file from which to read in information. Your terminal is also treated as the standard output file to which information is sent from the command. This action can be changed by redirecting standard input and standard output from and to any other file. Redirecting standard input . Redirecting standard output . Appending standard output to a file .

... Standard Commands . ... TwistedActor.Actor is core code for writing an actor: an instrument control computer (ICC) or hub-based script that does something useful.

... In real-time instrument control systems such as the AAO's DRAMA system, where relatively complex individual tasks control their own parts of a system (spectrograph, camera, telescope, etc), there are often significant similarities between tasks. ... DRAMA is written in C, but combines ideas from the X Windows Xt toolkit with its use of named actions in tasks to provide a successful, effective, inheritance mechanism. ... This action is used to set the simulation mode of our tasks. ...

... This method is called once when the filter is loaded. ... This method should return a flag word that specifies the filters capabilities. ... With CONVERT_TO_FLOAT, the filter is called with the image data converted to a FloatProcessor (3 times per image for RGB images). ImageJ will lock the image before calling this method and unlock it when the filter is finished. For PlugInFilters specifying the NO_IMAGE_REQUIRED flag and not the DONE flag, run(ip) is called once with the argument null . ...
