cppw  and cpgr will copy, with locking, the given file to /etc/passwd and /etc/group, respectively.  With
       the -s flag,  they  will  copy  the  shadow  versions  of  those  files,  /etc/shadow  and  /etc/gshadow,
       respectively.

       With the -h flag, the commands display a short help message and exit silently.
