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 similarly named 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 namespace as regular variables using the :FIELDS import
tag. (Note that this still overrides your core functions.)
Access these fields as variables named with a preceding pw_
in front their method names. Thus, $passwd_obj->shell()
corresponds to $pw_shell if you import the fields.
The getpw() function is a simple front-end that forwards a
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 access function
functions with their full qualified names. On the other
hand, the built-ins are still available via the CORE::
pseudo-package.
NOTE
While this class is currently implemented using the
Class::Struct module to build a struct-like class, you
shouldn't rely upon this.
