=head1 SYNOPSIS
|
26
|
|
|
|
|
|
|
|
27
|
|
|
|
|
|
|
Windows UAC (User Account Control) is the mechanism used by a program to request elevated privileges,
|
28
|
|
|
|
|
|
|
that is, to run as Administrator to make changes to the system. A program requests this when it is
|
29
|
|
|
|
|
|
|
executed, normally by means of a manifest embedded in the executable, which obviously doesn't work
|
30
|
|
|
|
|
|
|
for Perl.
|
31
|
|
|
|
|
|
|
|
32
|
|
|
|
|
|
|
Win32::RunAsAdmin allows you to fake this; you can detect if your script is running with elevated
|
33
|
|
|
|
|
|
|
privileges, and if not, you can request a restart with them. You can also simply use these tools to
|
34
|
|
|
|
|
|
|
run another process with elevated privileges.
|
35
|
|
|
|
|
|
|
|
36
|
|
|
|
|
|
|
This is still not a perfect solution, as Windows forces the new elevated process to run in a
|
37
|
|
|
|
|
|
|
separate console. But it's perfect for many purposes, would work beautifully for C-type
|
38
|
|
|
|
|
|
|
GUI programs, and still makes it easier to run I things as admin.
|
39
|
|
|
|
|
|
|
|
40
|
|
|
|
|
|
|
If you simply want to make sure your script is running as admin, invocation truly couldn't be simpler:
|
41
|
|
|
|
|
|
|
|
42
|
|
|
|
|
|
|
use Win32::RunAsAdmin qw(force);
|
43
|
|
|
|
|
|
|
|
44
|
|
|
|
|
|
|
Got it? Do you want to see it again? OK.
|
45
|
|
|
|
|
|
|
|
46
|
|
|
|
|
|
|
use Win32::RunAsAdmin qw(force);
|
47
|
|
|
|
|
|
|
|
48
|
|
|
|
|
|
|
But maybe you'd rather do something else before requesting a restart with elevated privileges.
|
49
|
|
|
|
|
|
|
|
50
|
|
|
|
|
|
|
use Win32::RunAsAdmin;
|
51
|
|
|
|
|
|
|
|
52
|
|
|
|
|
|
|
if (not Win32::RunAsAdmin::check) {
|
53
|
|
|
|
|
|
|
# Do some stuff...
|
54
|
|
|
|
|
|
|
Win32::RunAsAdmin::restart;
|
55
|
|
|
|
|
|
|
}
|
56
|
|
|
|
|
|
|
|
57
|
|
|
|
|
|
|
But be warned: be sure you use Win32::RunAsAdmin before importing anything else that might
|
58
|
|
|
|
|
|
|
affect the current working directory! Otherwise Win32::RunAsAdmin won't actually know what
|
59
|
|
|
|
|
|
|
your original working directory was. (It uses L to get the absolute
|
60
|
|
|
|
|
|
|
real command-line arguments, so that's safe.)
|
61
|
|
|
|
|
|
|
|
62
|
|
|
|
|
|
|
If you just want to use the infrastructure to run something else with elevated privileges,
|
63
|
|
|
|
|
|
|
that's simple, too:
|
64
|
|
|
|
|
|
|
|
65
|
|
|
|
|
|
|
use Win32::RunAsAdmin;
|
66
|
|
|
|
|
|
|
|
67
|
|
|
|
|
|
|
Win32::RunAsAdmin::run ($executable, $arguments, $directory);
|
68
|
|
|
|
|
|
|
|
69
|
|
|
|
|
|
|
This is also exposed as a command-line utility "elev" when you install this module.

Call this to run anything with elevated privileges. C<$executable> is the full path to the

96

|
|
executable, C<$arguments> is a string containing the arguments to be passed to the executable,
|
97

|
and C<$working_directory> is the directory to run the process in (defaults to the current

98
|
|
|
|
|
|
|
directory, obviously).

This provides a quote-escaped string for the arguments you passed, e.g. if your
