echo <percentage> | dbar [options] <indicator text>
DESCRIPTIONdbar 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.
- Label to be prepended to the bar (default: "" ).
- no new line, don't put '\n' at the end of the bar (default: do print ``\n'')
- Value to be considered 100% (default: 100).
- Value to be considered 0% (default: 0).
- Symbol represeting the percentage value in the meter (default: ``='').
- Number of charcaters to be considered 100% in the meter (default: 25)
EXAMPLESStatic 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% [=========== ]
for i in 2 20 50 75 80; do echo $i; sleep 1; done | dbar | dzen2 Output: Find out yourself.
