NAME
       byobu-ugraph - helper script for notification history graphs


DESCRIPTION
       byobu-ugraph is a helper script that can be used to create history
       graphs


USAGE
       byobu-ugraph [options] [command [args...]]


OPTIONS
         -f <file>   : File to read data points from.  (only required if no
       command specified).
         -h          : Show this help.
         -m <num>    : Minimum value (default=$min_default).
         -n          : Supress output of newline character.
         -p <points> : Specify number of data points in graph
       (default=$points_default).
         -r          : Do not rotate file <file> (default is to rotate).
       Option implies file <file> should not be written to so a command cannot
       follow script options in this case.
         -t <theme>  : 'byobu-ulevel' theme to use (default=$theme_default).
         -x <num>    : Maximum value (default=$max_default).


EXAMPLES
       Using byobu-ugraph to run a command, rotate log and display graph.

       Here we specify a command to display available memory.  Trailing echo
       adds a required newline Note no filename specified.

           byobu-ugraph "(/usr/lib/byobu/mem_used | sed -e 's/% //g';echo)"

       Using byobu-ugraph just to rotate log and display the graph

           file=/tmp/load.dat
           awk '{ print $1}' /proc/loadavg >> $file
           # Note: we need to specify what we consider to be a "reasonable"
       maximum load
           byobu-ugraph -m 3.0 -f $file


NOTES
       If you specify 'command', care must be taken with shell quoting to
       avoid expansion prior to this script running the command.

       If '-r' is not specified, the file <file> will be rotated such that at
       most <points> lines are retained on each invocation of this script.
