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 to read data points from.  (only required if no command specified).
         -h          : Show this help.
         -m     : Minimum value (default=$min_default).
         -n          : Supress output of newline character.
         -p  : Specify number of data points in graph (default=$points_default).
         -r           :  Do  not  rotate file  (default is to rotate).  Option implies file
        should not be written to so a command cannot follow script options in this case.
         -t   : 'byobu-ulevel' theme to use (default=$theme_default).
         -x     : Maximum value (default=$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 new‐
       line 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  will be rotated such that at most  lines
       are retained on each invocation of this script.
