volumectl - A configurable bash script that makes your life easier in controlling the brightness of your screen and
|
||||
notifying it at the same time.
|
||||
|
||||
Usage: brightctl [-v|--verbose] [-c|--config path] [-n|-N] -option [arg]
|
||||
|
||||
Options:
|
||||
-i [arg], --increase [arg] increase the brightness by the "normal" amount or by the [arg] amount
|
||||
-d [arg], --decrease [arg] decrease the brightness by the "normal" amount or by the [arg] amount
|
||||
-I, --big-increase increase the brightness by the "big" amount
|
||||
-D, --big-decrease decrease the brightness by the "big" amount
|
||||
-s arg, --set arg set brightness to arg
|
||||
--set-min-brightness set brightness to minimum
|
||||
--set-max-brightness set brightness to maximum
|
||||
|
||||
Optional arguments:
|
||||
--notification-timeout arg forces the notification timeout, in milliseconds (overrides the configuation setting,
|
||||
the default value is $NOTIFICATION_TIMEOUT)
|
||||
-n, --notification forces the notification to appear (overrides the configuration setting)
|
||||
-N, --no-notification forces the notification NOT to appear (overrides the configuration setting)
|
||||
-v, --verbose print each step the script passes through
|
||||
-h, -?, --help show this message
