dbar

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 ’\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% [===========              ]
