Abstract

A method is described to display only the logical file name for Data Management files and the physical file names for UNIX* files, and to display any additional Data Management specific information. With the addition of Data Management to the UNIX file system, the user can not see a list of the logical fields in the directory by the existing UNIX utilities. For every logical Data Management file there is one or more physical files that may or may not have hidden or derived names. The LIST utility uses Data Management functions to list all the files in a directory. It determines which files are UNIX files and which are Data Management. For UNIX it lists the physical file name, and for Data Management it lists only the logical file name.

Method to LIST Logical Data Management and Physical UNIX File Names

A method is described to display only the logical file name for Data Management files and the physical file names for UNIX* files, and to display any additional Data Management specific information. With the addition of Data Management to the UNIX file system, the user can not see a list of the logical fields in the directory by the existing UNIX utilities. For every logical Data Management file there is one or more physical files that may or may not have hidden or derived names. The LIST utility uses Data Management functions to list all the files in a directory. It determines which files are UNIX files and which are Data Management. For UNIX it lists the physical file name, and for Data Management it lists only the logical file name. It provides the user with an option (-a) by which the user can see the hidden files, Data Management or not, if desired. It also provides the user with an option (-v) to produce three lines of information about each file. The first line is identical to the line produced for any file with the -1 option, and the second and third lines are specific information for Data Management files. * Trademark of the American Telephone & Telegraph Company.
