PROGRAM:
NAME
battery-graph - Show a graph of the battery charge
SYNOPSIS
battery-graph [options] [files...]
DESCRIPTION
Show a graph of the battery charge over time.
The files given are assumed to contain battery statistics in the battery-stats(5) format.
If no files are specified, the default log files will be used.
The options can be used for displaying a different interval. An interval is defined in
terms of a from timestamp, a to timestamp and a duration. By specifying any two, the third
will be calculated automatically. A missing duration will be defaulted to 3 hours.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with
two dashes (`-').
-g geometry, --geometry geometry
Sets the X Windows geometry of the graph. This disables text mode. See X(7) for how
to specify the geometry.
-D display, --display display
Shows the graph on the given display. The same effect can be achived by setting the
DISPLAY environment variable. This disables text mode. See X(7) for valid values.
--title string
Sets the title of the graph window. By default this will be "Battery Graph". If
this is set to the empty string, gnuplot(1) will be allowed set the window title -
this can be useful if you want your ~/.Xdefaults to take effect for this.
-f date, --from date
Specifies the start date/time for the graph. This accepts exactly the same
date/time specifications as the date (1) command - see examples below or the
Texinfo manual for date for details.
-t date, --to date
Specifies the ending date/time for the graph. This accepts exactly the same
date/time specifications as the date (1) command - see examples below or the
Texinfo manual for date for details.
-s date, --since date
Shorthand for --from date --to now
-d duration, --duration duration
Specifies the duration for the graph. This can be given in units of seconds, hours,
days or weeks by suffixing the number with 's' (seconds), 'm' (minutes), 'h'
(hours), 'd' (days) or 'w' (weeks).
Units cannot be combined - e.g. '1d6h' will not be valid, whereas '30h' is OK. If
no unit is specified, minutes will be assumed.
--text Shows the graph in text mode on stdout. The resulting size of the graph is
determined by the values of the environment variables. LINES and COLUMNS (failing
that, the output from tput will be used). This is the default when the environment
variable DISPLAY is not set.
EXAMPLES
Show the last 2 hours:
$ battery-graph --duration 2h
Show the time since mid day:
$ battery-graph --from 12:00 --to now
or
$ battery-graph --since 12:00
Show the hour before last:
$ battery-graph --from '2 hours ago' --duration 1h
Show the 6 hours after noon:
$ battery-graph --from 12:00 --duration 6h
or
$ battery-graph --from 12:00 --to 18:00
Show the last 6 hours
$ battery-graph --from '6 hours ago'
or
$ battery-graph --since '6 hours ago'
Show the last 30 minutes in text mode:
$ battery-graph --duration 30 --text
Show statistics for Tuesday last week
$ battery-graph --duration 24h --from 'tuesday last week'
or
$ battery-graph --duration 1d --from 'tuesday last week'
Prove that the future hasn't happened yet:
$ battery-graph --from yesterday --to tomorrow
Another way of wasting CPU cycles:
$ battery-graph /dev/null
EXIT STATUS
battery-graph depends on gnuplot (1) to give the correct exit status.
