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.
