11 upsdrvctl [OPTIONS] {start | stop | shutdown} [ups]
12
14 upsdrvctl provides a uniform interface for controlling your UPS
15 drivers. You should use upsdrvctl instead of direct calls to the
16 drivers whenever possible.
17
18 When used properly, upsdrvctl lets you maintain identical startup
19 scripts across multiple systems with different UPS configurations.
20
21 Note: For operating systems with service management frameworks, such as
22 Solaris SMF or Linux systemd, the upsdrvsvcctl may be a better choice.
23
25 -h
26 Display the help text.
27
28 -r directory
29 If starting a driver, this value will direct it to chroot(2) into
30 directory. This can be useful when securing systems.
31
32 This may be set in the ups.conf with "chroot" in the global section.
33
34 -t
35 Enable testing mode. This also enables debug mode. Testing mode
36 makes upsdrvctl display the actions it would execute without
37 actually doing them. Use this to test out your configuration
38 without actually doing anything to your UPS drivers. This may be
39 helpful when defining the sdorder directive in your ups.conf(5).
40
41 -u username
42 If starting a driver, this value will direct it to setuid(2) to the
43 user id associated with username.
44
45 If the driver is started as root without specifying this value, it will
46 use the username that was compiled into the binary. This defaults to
47 "nobody", and is far from ideal.
48
49 This may be set in ups.conf with "user" in the global section.
50
51 -D
52 Raise the debug level. Use this multiple times for additional
53 details.
54
55 -d
56 Pass the selected debug level from upsdrvctl to launched drivers.
57
59 upsdrvctl supports three commands - start, stop and shutdown. They take
60 an optional argument which is a UPS name from ups.conf(5). Without that
61 argument, they operate on every UPS that is currently configured.
62
63 start
64 Start the UPS driver(s). In case of failure, further attempts may
65 be executed by using the maxretry and retrydelay options - see
66 ups.conf(5).
67
68 stop
69 Stop the UPS driver(s).
70
71 shutdown
72 Command the UPS driver(s) to run their shutdown sequence. Drivers
73 are stopped according to their sdorder value - see ups.conf(5).
74
75 Warning
76 this will probably power off your computers, so don’t play around
77 with this option. Only use it when your systems are prepared to
78 lose power.
79
80 Note
81 refer to ups.conf(5) for using the nowait parameter.
82
84 NUT_CONFPATH is the path name of the directory that contains upsd.conf
85 and other configuration files. If this variable is not set, upsdrvctl
86 the driver use a built-in default, which is often /usr/local/ups/etc.
87
89 upsdrvctl will return a nonzero exit code if it encounters an error
90 while performing the desired operation. This will also happen if a
91 driver takes longer than the maxstartdelay period to enter the
92 background.
