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.
