User::pwent - by-name interface to Perl's built-in getpw*() functions
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);
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() funtion 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.
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
