This is an excerpt from the latest version perlfaq8.pod, which
comes with the standard Perl distribution. These postings aim to
reduce the number of repeated questions as well as allow the community
to review and update the answers. The latest version of the complete
perlfaq is at http://faq.perl.org .

8.14: How do I modify the shadow password file on a Unix system?

If perl was installed correctly and your shadow library was written
properly, the getpw*() functions described in perlfunc should in theory
provide (read-only) access to entries in the shadow password file. To
change the file, make a new shadow password file (the format varies from
system to system--see passwd for specifics) and use pwd_mkdb(8) to
install it (see pwd_mkdb for more details).

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
