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 '\n' at the end of the bar (default: do print ``\n'')

-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.
