User::pwent(3) Perl Programmers Reference Guide User::pwent(3)NAMEUser::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.
