If you do not specify an output file Partlist sends the information to standard output which is usually the display screen 12 2 Schfiles Schfiles is a utility that lets you see a list of all the data file names used by a specified schematic or design file This list also includes the path for each file name Another useful feature of Schfiles is that it allows you to archive a schematic file and its associated data files Use the following syntax to invoke Schfiles schfiles OPTIONS FILENAME where FILENAME may be one or more schematic or design files Schfiles s default action is to display on the screen a list of all the symbol and schematic files associated with the specified schematic file If you specify more than one schematic file the list will include the files associated with each of the specified schematic files Schfiles lists the file name only once along with the complete path Each file name is printed on its own line The default search path of Schfiles is the same as that of Schedit so it will search for the data files in the same order that Schedit does Therefore if you changed your search path to obtain alternative files in Schedit either through the Search Path submenu of the Options menu or by using your own cad rc file you must change Schfiles s search path to match the one in Schedit See Appendix A Customizing CapFast for information on how to create your own cad rc file Schfiles options allow you
