Other Alias

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.


cppw and cpgr were written by Stephen Frost, based on vipw and vigr written by Guy Maor.
