Characters That Modify Special Macros

The following six macros all resolve to a file specification (or possibly several file specifications for $** and $?):

     $*     $@     $**     $<     $?     $$@

You can append characters to any of these macros to modify the file name returned by the macro. Depending on which character you use, parts of the full file specification are returned:

                               Appended Character
     File Part Returned      D        F       B       R

     File Path               Yes      No      No      Yes
     Base File Name          No       Yes     Yes     Yes
     File Name Extension     No       Yes     No      No
