dbar, (c) 2007 by Robert Manea
==============================
dbar is an application that generates semi graphical progress meters,
from some values you supply to it.
See the usage examples for a description of the expacted input format.
Options:
--------
-max : Value to be considered 100% (default: 100)
-min : Value to be considered 0% (default: 0 )
-w : Number of charcaters to be
considered 100% in the meter (default: 25 )
-s : Symbol represeting the
percentage value in the meter (default: = )
-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')
dbar lets you define static 0% and 100% marks with the '-min' and '-max'
options or you can provide 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.
Usage examples:
1) Static 0% and 100% mark or single value input:
echo 25 | dbar -m 100 -l Sometext
Output: Sometext 25% [====== ]
2) If your 100% mark changes dynamically or 2-values input:
echo "50 150" | dbar
^ ^
| |__ max. value
|
|__ value to display
Output: 33% [======== ]
3) 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% [=========== ]
4) Multiple runs:
for i in 2 20 50 75 80; do echo $i; sleep 1; done | dbar | dzen2
Output: Find out yourself.
