3.9.1 Basic usage for prt

The output provided by prt when no options are given is sufficient most of the time, and so it's common to use it without any options:-

     prt s.umsp.c

The default output contains slightly more information than the output of get -L. If you require more detail, the -e (“everything”) option produces more detail:-

     prt -e s.umsp.c

As usual, any argument that is the name of a directory causes all sccs files in that directory to be processed; the special argument - indicates that a list of SCCS files are to be read from prt's standard input.
