NAME

User::pwent - by-name interface to Perl's built-in getpw*() functions

SYNOPSIS

 use User::pwent; $pw = getpwnam('daemon') or die "No daemon user"; if ( $pw->uid == 1 && $pw->dir =~ m#^/(bin|tmp)?$# ) {     print "gid 1 on root dir"; }

 use User::pwent qw(:FIELDS); getpwnam('daemon') or die "No daemon user"; if ( $pw_uid == 1 && $pw_dir =~ m#^/(bin|tmp)?$# ) {     print "gid 1 on root dir"; }

 $pw = getpw($whoever);

DESCRIPTION

This module's default exports override the core getpwent(), getpwuid(),and getpwnam() functions, replacing them with versions that return``User::pwent'' objects. This object has methods that return the similarlynamed structure field name from the C's passwd structure from pwd.h; namely name, passwd, uid, gid, quota, comment, gecos, dir, and shell.

You may also import all the structure fields directly into your namespaceas regular variables using the :FIELDS import tag. (Note that this stilloverrides your core functions.) Access these fields asvariables named with a preceding pw_ in front their method names.Thus, $passwd_obj->shell() corresponds to $pw_shell if you importthe fields.

The getpw() funtion is a simple front-end that forwardsa numeric argument to getpwuid() and the rest to getpwnam().

To access this functionality without the core overrides,pass the use an empty import list, and then accessfunction functions with their full qualified names.On the other hand, the built-ins are still availablevia the CORE:: pseudo-package.

NOTE

While this class is currently implemented using the Class::Structmodule to build a struct-like class, you shouldn't rely upon this.
