dbar

dbar(1) 							   User Commands							   dbar(1)

NAME

       dbar - ASCII progresbar

SYNOPSIS

	 echo <percentage> | dbar [options] <indicator text>

DESCRIPTION

       dbar lets you define static 0% and 100% marks or you can define these marks dynamically at runtime.  Static and dynamic marks can be mixed,
       in this case the value specified at runtime will have a higher priority.

       You can specify ranges of numbers, negative, positive or ranges with a negative min value and positive max value.

       All numbers are treated as double precision floating point, i.e. the input is NOT limited to integers.

OPTIONS

       -l  Label to be prepended to the bar (default: "" ).

       -nonl
	   no new line, don't put '
' at the end of the bar (default: do print "
")

       -max
	   Value to be considered 100% (default: 100).

       -min
	   Value to be considered 0% (default: 0).

       -s  Symbol represeting the percentage value in the meter (default: "=").

       -w  Number of charcaters to be considered 100% in the meter (default: 25)

EXAMPLES

       Static 100% mark or single value input:

	   echo 25 | dbar -max 100 -l text

	   Output: text  25% [======		       ]

       If your 100% mark changes dynamically or 2-values input:

	   echo "50 150" | dbar
		 |   |
		 |   |__ max value
		 |
		 |__ value to display

	   Output: 33% [========		 ]

       If your value range is not between [0, maxval] or 3-values input:

	   echo "50 -25 150" | dbar
		 |   |	|
		 |   |	|__ max value 100% mark
		 |   |
		 |   |_____ min value 0% mark
		 |
		 |________ value to display

	   Output: 43% [===========		 ]

       Multiple runs:

	   for i in 2 20 50 75 80; do echo $i; sleep 1; done | dbar | dzen2

	   Output: Find out yourself.

ENVIRONMENT

       None.

FILES

       None.
